If you are watching a video on the Internet and you see an advertisement for Amazon.com, Netflix, eMusic, or Kayak.com, there is a pretty good chance that Adap.tv is behind them.  This week Adap.TV raised a $13 million round of funding in Series B.  Spark Capital led the round of funding and Dennis Miller joined the board.  Redpoint Ventures and Gemini Israel also participated in the second round.

Redpoint and Gemini provided Adap.tv with their first round of funding at $10 million.  Adap.tv plans on using this new round of funding to accelerate the development of their products.  Spark Capital are also investors in 5min.com, Covestor, Iminlikewithyou.com, KickApps, Me.dium, Tumblr, Twitter, and Veoh.

Adap.tv’s flagship product is called OneSource.  Through OneSource, Adap.tv can place product overlays, expanding overlays, video pre-rolls, animated overlays, banner overlays, and text overlays on top of videos.  One of the problems Google struggles with is making enough revenue on YouTube to help offset some of the bandwidth costs.  Adap.tv may be a good partner for the search engine company as it continues to find ways to embed ads subtly in the videos without pissing off users.
