CES: Kinect Sells 8 Million Units in 2010

Microsoft has confirmed that Kinect for Xbox 360 has sold 8 million Units worldwide between its November launch and the end of 2010 at their CES 2011 Press Conference.

Microsoft had previously said they were aiming to sell 5 million Kinect units between launch and the end of 2010 as a target; this was upped from a previous, lower target.

Steve Ballmer told the crowd at the CES press conference and the thousands watching online that 2010 was an “exciting” year for Microsoft thanks to the launch of products like Kinect. Kinect was also described as part of a Microsoft strategy of taking “big bets” on new technology. He went on to recount the history of Xbox and said that it was now “front and centre” of the social revolution.

Opening CES, Microsoft were quick to laud the successes of Kinect on stage. Kinect launched on November 4th in North America, November 10th in Europe and November 20th in Japan.

[vagina]

Wow...

[guigsy]

They're offensively high numbers.

[Hellsvacancy]

Shipped probably knowin MS

[DualConsoleOwner]

Its just the way the numbers are reported... there cant possible track sold to consumers accurately.

and they do this for every quarterly financial report. its always to sold to retailers or shipped to retailers. never to consumers.

why disagrees?? go check their financial report. geez. fanboys are so sensitive

[captain-obvious]

good numbers MS
didnt see that one coming TBH

but now im really worried about the next gen xbox

[Bigpappy]

And here I was thinking 6mil. Not even games don't sell that fast. My friends, Kinect is the next revolution in gaming. It is not needed for core gaming, but it presents and exciting new genre in gaming that inclues core and casuals alike to play and have fun. Sorry for those who hate other having fun but I see it as a great inovation. #2

[RememberThe357]

Exactly. Shipped or sold, those are still impressive numbers.

[LordMarius]

"It is not needed for core gaming, but it presents and exciting new genre in gaming that inclues core and casuals alike to play and have fun."

Where are these games?

[DualConsoleOwner]

where are the games you speak of??

and kinect is great for casuals and not so much for hardcores.

i hardly call it revolution since hardcore gaming will remain exactly the same. and casual is getting another new motion control.

[MariaHelFutura]

Now it`s time to produce the games.....this should be interesting.

[Retro_Zombie]

Gaming on rails is so sexy. lol Thanks for helping spur the economy!

[shoddy]

have fun playing with virtual balloon and tits.

[ComboBreaker]

a sad day for hardcore gamers on the 360.

[AndrewRyan]

Well the Kinect is fun... With friends...

No core games like Mass Effect or Uncharted but just for fun times, Kinect is where it's at.

[DSI]

*Cricket*......*Cricket*...... *Cricket...... :)

[Aquanox]

Wow! that double tha amount move sold in the same period.

Microsoft Xbox is on fire!

[deadreckoning666]

Okay guys, lets approve this TWICE like the "GT5 ships 5.5 million units worldwide" article. Fair is fair. See I can be inconsistent hypocritical ignoramus too :)

@brohuffman- LOL, I kno rite.

@Bigpappy- More evidence that the opinions on N4G don't mean a damn thg. Even if Kinect does extremely well this year, Sony fanboys will always refer to the "$500 advertising" spin. What a stupid argument. It holds just as much weight as me saying that the only reason the PS3 is selling so well is because of its price point.

@kingjoker34- If Kinect sucked, don't u think word of mouth would have put the device 6 feet under by now? LOL, the fantasy these people live in on this site is astounding.

@Saga Kin- HAHAHA, the N4G time machine strikes again! Saga Kin has traveled to the future and has found that Kinect will NEVER achieve implementation with fun hardcore games.

I don't know whats worse the fact that you think you know what Kinect will be capable of in the future or the fact that ur speaking for ALL gamers as if they shared the same cult-like mentality that you have on this site lol.

[oldjadedgamer]

Haha, some people just don't understand humor.

[MariaHelFutura]

You have serious problems....you worry way to much about what other people are thinking and what concerns them.

[N4WAH]

dead if you are of drinking age kick back a shot of something strong like bourbon. You are posting a lot of venom tonight man. What gives? You take this crap too seriously. These are gaming devices and it's a form of entertainment, not a battlefield.

WTF is the matter with most members on this site?
Now I see why I all but stopped visiting here.

Back to my hole in the world and to gaming, you know, for fun?!

[Parapraxis]

....but you ARE an inconsistent hypocritical ignoramus.

[Dragun619]

Well, that's what happens when you spend $500 Million on marketing for Kinect.

[DSI]

Haha, hate all you want but 8M X $150 = $1.2B - 500M = $700M profit. (Rough numbers)

Looks like 5M was worth it, especially since it's only been two months.

Perhaps Sony should spend 500M on something.

Just saying.

[captainjy]

So they spent $500 million to make 1.2 billion and profit $700 million. I would take that any day of the week!

[UCMEandICU]

So forget about research and development, forget about packing and transportation, forget about 3rd party distribution outlets, just let's look at advertising costs.

8million of these cameras sold is unbelievable and I am totally flawed by how effective MS is with their style of bullish marketing.

They know their base & human nature very well.

[thewhoopimen]

That is some pretty retarded profit calculations... 700m profit... snort* lol.

Kind of forgetting cost of materials, labor, and all your accounting basics aren't cha.

I guess FedEx, UPS, or whoever MS uses to ship these products must be doing it for

sh!ts & giggles

[kingjoker34]

yea well when you spend $500 mil on advertisement what do u expect? now how much u wanna bet with the profit none of it is going to new game devs?

[Tinasumsum]

Developers from all over the world where lining up to develop for Kinect before it even launched. Kinect's success will bring in revenue for both 360's standard and Kinect games.

[blumatt]

...but the fact remains that it's gonna be very difficult to implement Kinect into core games unless they come out with some Move-like controller like Sony. I'm betting the next Xbox will have some sort of motion controller to go along with Kinect 2.0 if not before then. Off topic, I bought that Kung Fu Live game and I have to say that it's cool how you can pay $15 for a game and only $40 for the PS Eye and play the same type of game that Kinect offers for a cheaper price. Of course, I don't play the game that often, only when someone comes over.

[lowcarb]

Kungfu live is not on the same level as a Kinect game. Try kinect and then get back at me when you see just how huge the difference is.

OT:Good job MS!

[blumatt]

Ok I'll put it to you this way. It does something I haven't seen done in a Kinect game. It put YOU in the game. It takes your body and somehow green screens away your background and shows you on the screen. It's pretty cool, man. Also, even if Kinect is a little better, it's not so much better that it needed to cost $150. The Eye is only $40. Can you honestly tell me Kinect needed to cost almost 4 times as much as the Eye, or that Kinect is 4 TIMES as much better than the Eye? That's my issue with Kinect, the price. Plus Kinect games should be $40 a piece like Move games.

[Droidbro]

Stop lying. The eye is 40 dollars yes. Are you saying the controllers are free?

[blumatt]

No, I'm referring to the Eye's ability to play motion games like the Kinect. I'm not referring to Move games. I'm referring to games like Kung Fu Live that is just like Kinect games (maybe slightly less accurate) and it only costs $15 for the game and $40 for the Eye instead of $50 per game (Kinect games) and $150 for the Kinect. Kinect is overpriced. Simple as that.

[Droidbro]

Oh, so you're comparing a cheap webcam to kinect? got it

[blumatt]

Well, if you want to put it that way, my cheap webcam does almost the same thing as your Kinect. And at only a quarter the price. Pretty sad, man. The Kinect should not cost $150. Simple as that. It should cost $50 at the MAX.

[nsnsmj]

Holy crap! It caught me off guard when I saw that. Definitely didn't expect that many sales. That marketing was genius. Oprah, Ellen, $500 million, etc. Sony needs to take a page from MS's book in this area.

Anyway, good job MS. While I still don't think Kinect is actually anything great, others in this world obviously do. Marketing speaks! That is all.

[State of Matter]

Yeah WOW is what I said too when I heard this, I didnt think they would make the 5mill they wanted, plus they said 50 million 360s have sold world wide, 360 is a beast, its only a matter of time before it passes Wii at this rate.

No I thought wii was at 60 mill, sorry. 360 will still catch up just not before Wii2

[oldjadedgamer]

Let's be honest, the wii is a beast that will not be past while both the wii and 360 are their main consoles.

Not saying the 360 won't pass the wii eventually, but I assume the wii2 would be out.

[KILLERAPP]

State of Matter:

You do know the wii has sold over 75 million consoles right???

[Anon1974]

Wow. I was so far off on my prediction on this. Kinect did way better than I ever thought it would. It'll be interesting to see if interest in it stays strong after the holidays, and if the games on it do better than the way casual have been purchasing games on the Wii. Well played, Microsoft. Motion gaming certainly isn't for everyone, but I never would have believed something like Kinect could have moved that many units when I saw what they had to offer at E3 this year.

[Mahr]

I imagine a lot of N4G users are on suicide watch right about now.

[Stryfeno2]

WOW!!!!!

[Tinasumsum]

Way more than I thought. I was guessing 6 or maybe 7 million. Good job Microsoft for supplying demand and doing such a good job after they first where selling out people were saying Kinect wasn't selling. So much for the I see them everywhere DC

[-Alpha]

What was their 2010 goal again? 5 Million? 10 million?

Edit: Well then you have to hand it to them, they know how to market their product

[SixZeroFour]

5mil by the end of the year

pachter said 11mil combining both move and kinect by the end of the year

[Tinasumsum]

It was 3 million and when the pre-orders took off Microsoft predicted 5 million but anybody could see the way it was selling 5 million was off.

[Tony-A]

They say sold. It's sold, right? Shipped/Sold? Does sold mean sold and shipped mean sold? Is that for one company? Not entirely sure anymore thanks to this community.

Anyway, I was guessing right between their goal and their actual number. If I were a corp business, I would tell people we're guessing lower than we're actually guessing to make it sound like we blew our expectations out of the water. I'd say it's a great technique cuz it works.

[kissmeimgreek]

Im guessing so... They said they beat their estimate of 5 mil SOLD so im assuming 8 mil is for sold as well.

[-Alpha]

I thought sold always meant shipped. Can I please get a definite answer because I swear people constantly interchange the meanings.

[Non_sequitur]

When merchandise is shipped it must have been ordered by a retailer. At the end of the month the retailers pay for what they ordered. Even if there are some still on shelves at the end of the month it still counts as sold for the company who sells the merchandise to the retailer. To find out how many consumers actually bought it is much harder; unless every company had a perpetual inventory system and disclosed sales information in real time.

[thenickel]

SO basically all companies use this tactic because there is no way in knowing just how many were sold to consumers.

[Spenok]

Shipped, theres a new article up where MS confirmed to IGN these are shipped numbers.

[KILLERAPP]

Wow... Congrats MS…

[mightyboot]

i predict less than 8 million this year

so i guess 8 million kinect users have kinectimals or kinect´s joy ride O_o

The casual games market is proving to be the next M$ way of cash.

[Forbidden_Darkness]

Naw, they're all dancing with Dance Central!

[mightyboot]

Oh that explains alot.

[Balt]

Love this part:

"Taking big bets on new tech"

I almost laughed myself silly -- Well, sillier than I already am.

"Taking big bets on old, un-proven, un-explored tech"

That is what he should have said. Microsoft has duped a sea of people yet again. I wonder what happens when the mice they lead catch onto the pipes pitch? You know, the one that doesn't change.

Face it, what Microsoft has done is no different than someone taking 16 bars of a song and working it into their own material. They then re-brand it and resell it. People buy it in droves thinking it's new, when in reality it's always been there. It just wasn't presented or forced down your throat as much the 1st time.

[badboy808]

MARKERTING!!!!!!!!!!!!!!!!!!!!

[CarnageXB]

Thats just the first 60 days. Thats amazing

[GaMe01]

It proves that if you take a product a company failed to shine on and re introduce it bigger and better it will sell

[State of Matter]

Well Im not so sure about that, if your talking about eyetoy I had that, and I have kinect, kinect is way better, and far more amazing in action.

Eyetoy would not have sold like this even if Sony spent a billion on advertising, it just wasn't that great.

[Forbidden_Darkness]

8 million people have Kinected to a slightly new experience. That's great news! ;)

/s

[NYC_Gamer]

all that marketing paid off

[Tinasumsum]

Word of mouth is killing Microsoft's ad effort. Word of mouth is helping Kinect sell way more.

[gypsygib]

Very impressive seriously!

I still don't want one.

[Raven_Nomad]

Guess it's safe to say it's not the next 32X eh guys? Congrats to Microsoft.

[oldjadedgamer]

Not surprised, they were sold out in most places.

My parents got one for my little brothers without really knowing what is was. They got it because it was the next big thing for the system.

Turns out the games aren't that bad, fun for company. Not that I would be able to afford one for myself or have the desire to buy one.

[Arup02]

Wow, really impressive numbers. MS sure knows how to do marketing, not like s*cough*

[Shazz]

congrats , if they say it SOLD then i believe them the same way gt5 sales are sold coz i dont think companies are allowed to lie to potential investors about sales are they ?

[jukins]

of course they're not but they are allowed to twist words in anyway to make it sound good to customers/investors without telling the entire truth. 8 mill kinect sold seems a little outrageous to me. i find it hard to believe that a bigger deal was not made i about this i mean thats more than xbox 360 or ps3 call of duty numbers isnt it?

[StarScream4Ever]

Congrats but don't forget about the real core audience!!!

[Arup02]

True, we want games!!!

[StarScream4Ever]

When we bought the 360 we were promised a future of hardcore gaming with titles like Halo, Call of Duty, Forza, Bioshock, etc. Now it's all about social media and Kinect. What the hell?!

[m23]

We'll get some games this year, they just haven't shown everything. At least I hope so. Either way this fall is so packed as it is. There's Gears 3, Elder Scrolls, Ghost Recon, as well as some more I'm too lazy to name.

[StarScream4Ever]

@Munish. There needs to be more than multiplats. There's got to be heavy exclusives that 360 copies would proudly be stamped Only on 360. Now that lost all meanings.

[thenickel]

Even Kinects line up sounds impressive this year with games like Draco, Star Wars, Codename D (all great developers by the way)and a possible Steel Battalions. The games are coming and will be fresh and new. E3 will get here and I have a feeling MS finally will show off some good stuff. Sure we haven't seen footage but Forza 4 and codename kingdoms might seriously surprise.

[Forbidden_Darkness]

Good luck with that ;)

[Dogswithguns]

Kinect is awesome.....

[Raven_Nomad]

Let's not forget that OVER 50 million XBox 360's have now been SOLD as well. Good for them. Not a bad outing for MS.

[Rageanitus]

thats pretty impressive, though I see alot of kinects on the shelves... maybe they overstocked during christmas rush

[thenickel]

Or maybe you live in Japan. USA is hard to get them still in many places.

[prettylookingguy]

i think every side got a new year gift from god of gaming

while sony fans celebrated a magnificent game called LBP2, 360 fans also got their own celebration of kinect's amazing sales

happy gaming to all gamers and salesman on n4g, cheers!

[FrigidDARKNESS]

thats 8million sold to retailers not to consumers

[MaideninBlack]

When Microsoft reports sales it sold to customers! Shipped to retail only applies to Sony.

[mynd]

@ Frigid -Yes, likely. But its stil twice as much as *ahem* sold to retailers in the same time.

@Madin, no generally they both state shipped. MS's first number after Black Friday were apparently "sold to consumers" but outside of that its generally "sold to retailers".

[MaideninBlack]

I know. I was being sarcastic.

[MaideninBlack]

Too bad nothing on the software side of Kinect has sold a fraction of hardware sales.

[Raven_Nomad]

Isn't Kinect Sports closing in on 3 million? Plus Kinect Adventures is packed with it, so 8 million copies of that game have been technically sold. Dance Central also went Platinum.

[Tony-A]

Yet VGC reports under 3mil for Kinect Adventures.

You gotta love numbers! Sales this generation are about as unknown as any mythical creature. For all we know, everyone could be making numbers up.

[Spitfire_Riggz]

The interesting thing is with the PS3 being jailbroken how it is we will likely see Kinect on the PS3, Now i'm not saying its good or bad but it will be interesting to see how it affects the Kinects sales. One thing is the ps3 wiill have both motion sensors which might give itself a boost. Word of mouth

[EvolZero]

You were joking right? The PS3 will not see legitimate Kinect integration. Even if it's just homebrew, I can't see it being nearly as refined or useful for any games getting released on PS3. Its all about the Move for Sony. The codebase is already there.

[Spitfire_Riggz]

YOU'VE got to be joking, of course you didnt think I meant Sony would start making games for Kinect right??? THe kinect has been enabled for the PC which could easily make it work for the PS3. We wouldnt use it for games but for all that crap hackers have used it for. It hasnt even been used for games on the 360. We would have PS3 hackers working on it too, maybe homebrew could make it useful

[EvolZero]

Just because something easily works on the PC won't make it such an easy task to make it work on PS3. Drivers are OS specific, unless every piece of software they code has a new PS3 specific Kinect driver. No one will code a full on game for PS3 utilizing Kinect. Media player or Xmb modification use at the most. That's if someone decides to takes the time to develop PS3 specific code for the sensor. And since u seem to forget hackers and coders like to have motivation to do it.

And it has been used for games on 360.....you know the ones that people are playing, doesn't matter if the titles don't appeal to you, it's still valid software.

Why is it every time I come to N4G I feel like my IQ needs to be lower to understand some of the things people suggest.

No one is dumb enough to believe Sony would make a game using Kinect. Hackers are more likely to use what's already there. Move along now.

[despair]

pretty impressive sales, taking into account the cost of the hardware being something like $50 and the 500 million in marketing, they probably already broke even or made a profit on just hardware sales, and that's not even counting software yet.

[jukins]

i doubt they've recouped the 500 mill advertising let alone the initial dev budget. i can say retail stores are making about 14-15% off kinect which means they're buying it for around $125 maybe making microsoft about $25 per kinect if that

[despair]

The parts cost was broken down by an independent group(can't remember who) and came somewhere near the $50 cost. Taking that into account and your estimate of $125 sales price then its:

8000000 x (125-50)= 600 million

So minus the 500 million advertising and you still have 100 million in profit, of course there are other cost to consider but I'd say that leaves them close to breaking even and with software sales to take into account they probably made a profit.

[jukins]

the game included also adds cost. . . . .

[thewhoopimen]

Aren't you forgetting, labor (assembly, design, R&D), packaging, shipping and distribution? I would venture to say that MS is still in the red at this point.

[Close_Second]

Ok, now support those people who have supported Kinect by releasing some real killer titles for it. Sony had every opportunity to make the PS3Eye a success on the PS3 but they did nothing with it until MS came along with Kinect.

[Darth_Bane79]

I still wouldn't get either move or kinect. When I play I want to chill after work, not jump around and be standing up, my feet are already tired from working all day.
I guess motion controllers are good for kids tho, so they can be active and all that..

[gypsygib]

I hope Kinect makes me happy I also own 360 this year, the exclusive sure doesn't.

[EVO-OM3GA]

Well Done To MS

[The real killer]

Microsoft lie, they love lie to people. It's just shipping nummbers.

If you see the software for kinect, it has nowahere as 8 million copys.

[hoops]

And Sony NEVER lies...NEVER...about shipped vs. Sold...etc.
Good god Real Killer. What are you...5 years old?

[OC_MurphysLaw]

Oh N4G...thou do love to hate. Kinect announced...the massess say it will flop... MS raises their forcast to 5 million and the massess here say... no way. MS sells 2.5 million in its first 30 days and still the massess here say it will never keep going and they wont hit 5 million... What now N4G? Its at 8 million in 60 days (shipped or sold doesnt really matter)... 8 million.

[JonnyBigBoss]

It's a sad day for the gaming industry. Thank goodness Sony is here to deliver core games like LittleBigPlanet, Killzone, inFamous, SOCOM, The Last Guardian, Uncharted, and Twisted Metal.

[theIMP]

I don't know what it is about your comments, but they make me want to punch someone in their fucking face. Why are you in every Kinect/360 article if you hate them so much? Fuck, I know I could live without seeing your 1 sentence opinions, and fucking list. We get it though. You LOVE Sony, and you've made it very clear. Why don't you go ahead and take 2011 off, and stick with the PS3 articles. I mean what the fuck is the point of posting in these articles? Do you think you are convincing anyone not to buy a product they want? I doubt anyone will read your comment and said to them self’s, "Gee whiz, I sure did like my 360 until jleack posted his amazingly insightful comment and showed me that my opinion is shit, and I should run to the nearest GameStop and sell this bullshit console to buy the almighty PS3". I just don't understand any of ya'll that have to post this shit daily, I mean get real man.

[jalen247]

Congrats to Microsoft...1/2 a billion in advertisement goes a long way...Kind of new it was going to start selling like hot cakes once my female friends and sisters started to ask me about Kinect...Females watch a lot of TV and are as casual as they come...

[jootca]

The majority of the sales were from people who already had 360's. It didn't push many units!!!

[testerg35]

LOL.. what next.. when 360 shows a ton of sales in December, you're gonna blame Kinect and then use the excuse that it won't last? Which would then contradict what you said... oh wait.. that's what PS3 fans do.

[bailoutbenny]

looks like some fanboys might need a little of this:

http://www.mountainside-med...

[Omega Zues]

WOW 8 million sold! Thats so cool! Sweet! I cant wait to tell all the guys! AND OH WOW! Avatar talking! Thats so dang swweeeeet! Yeah, cool wooohooo!

....

And Gears 3 still seems so..so so, far away.

[prime69time]

It was shipped not sold so who really know's now. MS spokesperson let IGN know it was shipped.

http://xbox360.ign.com/arti...

[baodeus]

They all use ship numbers including Sony.

8mil is still pretty impressive. I like it, but thought that 5 mil would be a pretty high goal for them this year. Who would have thought.

Again, why would it be a sad day for game industry? Xbox is capable of core game isn't not? People don't really think do they.

[STREET x KING]

holy fu*k!! That is insane numbers for kinect!!!!!! I bought one myself and its pretty cool!

[YOUR-MUM]

Honestly guys, check my gamer tag which is THEBIG360 . You will see I have completed the halo games the gears of wars , forzas and mass effects. So I would class my self as more than a casual, however I have bought kinect and love it . Ps3 trolls just need something to moan at , the big thing at first was the lag . Guess what it really dosen't effect gameplay ,hardly noticeable . So now it must be the lack of hardcore games, Jesus get a life and go play little big planet 2 which is awesome rather than trolling on here.

[ufo8mycat]

8 million aye. I guess that explains Microsoft's lack of enthusiasm to release QUALITY core exclusives.

I guess you can't blame them, since casual games is where the $$$ is. Sucks for core gamers though.

Looks like the PS3 is the only hardcore platform left.

Theres already enough kids on XBL. Now it's going to go overboard with screaming kiddies.

[jetlian]

pretty fun. I don't know why people still hating on it. if you wanna talk that its sold to retailers you need to do the same with 4.1 million moves. so for all the people thinking 3 million kinects on shelves same could be said about move

[Sizzon]

It was shipped.

http://xbox360.ign.com/arti...

[AceofStaves]

Shipped means sold to retailers though. Retailers don't order in stock that won't sell and will just gather dust. Shelf space is too valuable. So either way, MS has sold those Kinect units.

[captainjy]

Greenberg said this on twitter:

"@therealcliffyb We have no channel inventory, so essentially the same #....every Kinect we make we sell."

[Lykon]

i've had all the kinect I wanted when i brought a webcam for my pc 10 years ago, was fun popping bubbles for about 30 mins... 8 million! wow . mind you theres not much else to buy for 360 atm.

[captainjy]

What have you been sniffing? I don't know about you and your PS3, but I have tons of stuff to play on my 360.

[lelo2play]

That's a hell of lot Kinnect's sold in 2 months.

[Sidology]

So...Sony Glowing Sex Toy is considerably crushed.

[ASSASSYN 36o]

Eyetoy my ass. There is clear indication a market is alive and well for kinect. It is not in the shadow of the eyetoy. It is a unique device with unique capability. I have been saying since the public beta days of kinect that it works months before release. What say you haters now?

And how long are we going to play that, "it has no games song?" Everytime something popular releases that is all that is said! It has not been out that long. People say that with every console or peripheral ever released that they don't like knowing damn well the games are inevitable. With success of course. And kinect has it.

And this sudden fear of an assault on hardcore games is fully retarded. I don't get why people feel so damn threatened. Core gaming has been widely available well before kinect was ever heard of.

[AceofStaves]

Unfortunately, the people who want to fight over consoles will do so, regardless of the facts. They change their arguments to prop up their side and make the 'enemy' look 'bad.'

Why can't the 'console warriors' accept that all 3 companies can be successful at the same time? Kinect has sold very well. Move is successful as well. It's not an either/or situation.

My nephew received a Kinect for Christmas, and he really enjoys it. It's a shame that I can't use it, but I'm glad some people are having fun with it.

[Muffins1223]

And what are they gonna do with that money,probably spend it down a drain for advertisement
