The website is Ulive.com and right now has 75 different Food Network shows available for viewing. Some of the shows have full episodes plus shorter clips available, while other shows just have short clips. The 75 shows are a mix of both current shows like Barefoot Contessa, Restaurant Impossible, etc, and shows that have been on in the past. However, many of the past shows have a single clip and not full episodes.
Also available are Cooking Channel shows, Travel Channel shows and Original Series. So if you don't currently have the Cooking Channel as part of your current cable package, you can take a look at the 51 shows available there, or watch Travel Channel shows like Rachael Ray's $40 a Day.
Scripps seems to now be embracing the digital world with the launch of this website, and their earlier agreement with Amazon to have episodes of many shows on Amazon's site.
