It links you to a number of TV stations and offers clips and even full episodes. For the most part, they don’t look bad at all, providing you can find shows you like and want to watch.
The trouble is that there’s not a lot of actual content available on TV.com, despite it appearing to link to many channels. There seems to be fair support for some CBS shows, but most of the other categories are a little desolate.
Since TV.com is free, it’s worth a download to see what’s on it and if you’re interested. Unfortunately, it’s not going to replace similar subscription-based services anytime soon.
