—Bloomberg TV to use Google TV Ads: Since exiting from beta this summer, Google TV Ads has been trying to make the case for its self-serve, targeted ads to pay TV networks and marketers. Financial news network Bloomberg TV is going to give Google (NSDQ: GOOG) TV Ads a go.

That only gives Google access to the satellite TV company’s 14 million households out of a roughly 65 million basic cable subscribers, according to figures from the National Cable & Telecommunications Association. Given the hunger for economic news due to the volatile financial markets, the Bloomberg deal could hardly have come at a better time for the search giant.
