The Nielsen Company want to track your stats. Specifically, the two companies have teamed up to "develop a measurement system for game network advertising that will help make game software a more competitive advertising platform," according to the press release.
SCEA will "share with Nielsen game network traffic and other data" from PS3 titles, PlayStation Network and the upcoming social MMO Home, at first only in North America -- details beyond that are sketchy, but Nielson calls the effort "fully-transparent" in the press release. The results will be used "to deliver the right ad to the right person at the right time" and to help advertisers figure out a CPM, or cost per impression, for in-game ads.
The initial results of the partnership are expected later this year. Expect more in-game ads you're less inclined to ignore and possibly the strange feeling that Big Brother is critiquing your gamer skills.
