Is Gaming Finally in the Mainstream?

There was a lengthy period where gamers were considered nerds or geeks, and many stereotypes were formed around that opinion. In current times, it is difficult to find a household without at least one console in it. The Wii has sold over 75.5 million units worldwide, followed by the PS3 at 43.4 million, and the 360 at 42.9 million. And even if a household does not have a console, you are sure to find a couple games on their phone. And if not on the phone, people have started to play several games on social media networks, such as Facebook. What brought about this change? Is it finally safe to say that gaming is in the mainstream?
