Here is an article about cbs starting to have there shows available free through the tv.com app.

I am a true slickdealer and hate paying the $1.99 an episode so here is a solution for a few shows anyways. Also nbc.com has free episodes available for the iphone as well.

There is also Joost app as well

Thanks, tv on the go
