The word dip in the headline of course refers to the seven months of lower than expected game sales that the industry has been experiencing, and not to the concept of video games just finishing up a swim in the pool. That would be ridiculous, it's December. It's too cold to go swimming.
The industry as a whole has experienced an 8% increase in sales, compared to last year according to NPD. Video games took in $2.99 billion dollars in revenue during the month of November. Much of this rise in sales is thanks to the massive successive of Call of Duty: Black Ops. It pretty much sold more than anything ever, selling 8.4 million units. Assassin's Creed: Brotherhood and Just Dance 2 came up right behind Call of Duty: Black Ops in first and second place respectively, in regard to units sold.
