Last week at Google I/O, we witnessed the unveiling of Google TV. One of Google’s launch partners is DISH Network, who will offer the service to its customers beginning in the fall, via its HD DVR receivers.

Google’s relationship with DISH Network goes back much further than this announcement, however. Since 2007, the two companies have had a partnership around Google’s TV Ads, the television advertising arm of its AdWords service. Google has now announced that this relationship is expanding.

"For the past three years, DISH Network has been one of Google’s strongest partners in the TV advertising space," says Google TV Ads product marketing manager Neha Mandal. "Back in 2007, DISH embraced our emerging TV ads platform by signing on as our first partner and has since been an innovative thought leader with Google throughout the growth of this business."

"We’re happy to announce that we’ve renewed and strengthened our partnership with DISH Network and will continue to offer great inventory across over 95 networks on DISH," adds Mandal. "Through Google’s TV Ads platform, advertisers can continue targeting audiences across networks like Animal Planet, CNN, MSNBC, NFL Network, TBS, USA and over 90 others."

Google says to be on the look out for more new features and targeting options coming soon to the Google TV Ads platform, which is just one of many ways you can expect Google to continue its penetration into television advertising, if Google TV becomes as big as many are expecting.

In a recent article, we looked at how Google might accomplish this. The company seems to view moving into the TV format similar to what it has already accomplished with mobile via Android. Google says it will likely develop new ad formats for Google TV in the future, but at first they’re just concentrating on delivering a good product.
