As an auction-based system, Google TV Ads gives the ability to target different audiences by income, household composition, location and other demographics. Specify your budget and Google calculates how many impressions you can expect.
Google TV Ads will appear on satellite or cable TV networks, depending on the networks or programs that you choose in your TV campaign, but your ads will only show if your CPM bid is high enough to win the ad auction for the networks and times chosen. Ad placements are ordered through Google, but your ads will appear just the same as if you bought the inventory directly through a television company.
Detailed TV ad reports are available the day after your ads have run. Reports include actual impressions and audience tuning behavior that bring a new level of measurability and accountability to television advertising.
