Google is good and all but most of it's video search results are from Google Video and YouTube. Both of those services have nearly been stripped clean of any broadcast television shows. Those shows do exist out there and many in their entirety. That's where Blinkx comes in.
It's the worlds first GOOD video search engine. I know it's good because I searched for Tiny Toons (one of my favorite cartoons growing up) and received listings from almost every season. The integrated player only gives you a short preview. Clicking on it takes you directly to the source. I've also found the service useful for past news stories. It seems somebody, somewhere decided they would record and catalogue everything off TV.
I also think it's cute that their logo is as colorful as the city they were founded in; San Francisco.
Merged with joost and you have the ultimate home TV thing...
