Videogame advertising network Massive has just announced signing 12 advertisers and is slated to place ads in 40 titles, reported MediaPost.

Massive signed a deal with Nielsen to use Massive's software to track how often a player comes across the in-game ads and report stats back to the company over the internet, according to The New York Times.

Ads will be dynamically updated through a PC or console system's internet connection, allowing advertisers to target by geography and change ads over time.
