Google ads games network to adsense

Yesterday Google announced a game network to it’s Adsense platform. All the games are online (of cource) and formats appear to be in between levels, before and after the games.

According to New Media Age:

Google said it will sell ads to “top brand advertisers” to increase click-throughs and thereby revenues for the publisher.

I’m a but confused. Is brand advertising not supposed to be above trifling issues like sales?

Below the Google video that promotes the service.
