In-game ad spends

From eMarketer:

"Globally, it's estimated that video game advertising will grow nearly 23% a year over the next five years. The main reason? Everyone is playing."

From the MIT Adblog:

"eMarketer projects that $295 million of the 2007 total will be spent on in-game advertising and that spending on advergaming (the creation of games for the purpose of promoting a brand) will reach $207 million. By 2011, the balance between the two will have shifted significantly. US spending on advergaming will climb to $344 million in 2011, but US spending on in-game advertising will climb faster, reaching a total of $625 million that year."
