Google is on the verge of signing a deal with Dish Networks to deliver TV commercials, according to VentureBeat, which cites a rumor reported in the Wall Street Journal.

The rumors of a Dish Networks deal come just a day after reports were confirmed of Google's testing TV ads in Concord, California. But delivery over Dish Network's system would allow the commercials it serves up to be better targeted and relevant to what people were watching.

There's also the issue of interactivity. Dish operates one of the most interactive networks in the country, allowing users to search by keywords and define their programming according to their tastes.

All of that is data that Google could potentially mine to serve up ads that appeal directly to the viewers.
