The 3rd party extension allows you to watch free online TV channels. I could see some, however, majority of them don't work. That's fine. This stuff is still nascent.

Then, Google has their TV ads product - http://www.google.com/adwords/tvads/

Now, what if Google starts to use this into the internet TV (or has it started doing it already, don't know). A TV content generator or a TV channel can offer free channels and have Google Ads giving them the ads plus revenue. However, the share has to benefit the channels to offset their content generation cost.

To summarize, we might see a free TV world with Google Ads and Google in this way will get another stream to add revenue to their already fat pocket.
