Comparison of iTunes video and Google Video Store
He says that overall, Apple offers the better experience for consumers who want to buy digital versions of TV shows:
I applaud Apple for giving users far more latitude with the videos. Unlike Google, Apple users get permanent access to prime-time shows they buy, not just for 24 hours.
Additionally, Apple's customers are free to download shows to video iPods and burn them onto DVDs. Now that's convenience.
Overall, I give Apple's paid video service higher marks than Google's. If Apple solved the problem of slow downloads and added a bigger selection of video, then I would be a more frequent customer.
But my accolades have their limits. Given a choice between paying for online video or watching a show free on television, I'd choose the free television every time.
