Google has jsut announced an early trial of TV ads.

From the press release

 “With Google TV ads, the entire process is automated – from planning the campaign to uploading and serving the ad to reporting on its effectiveness. Like our AdWords advertising program, Google TV ads are bought using an auction model… 

“Advertisers can target by demographic, daypart and channel and pay only for actual impressions delivered. Pricing is on a CPM basis.

“Because the entire process is automated and online, advertisers can plan their TV ad campaigns efficiently all year long.
