Blinkx, the online video search engine, has launched a new feature called Blinkx Remote which is basically a list of different TV shows that you can watch online.
Blinkx Remote will let you know what TV shows are available to watch online for free (& legally) with a picture of a little TV screen.
Blinkx Remote will also let you know if the shows are available to purchase, such as from the iTunes store, with a picture of the $ sign.
It also lists video clips from around the internet for whatever TV show you are looking at. Some of the clips may even be full episodes too.
