CBS signed an exclusive deal with Amazon to provide the show to Amazon Prime subscribers in regular format as well as HD. Amazon Prime members will be able to stream episodes of the show four days after they debut on CBS, while anyone with a credit card will be able to download episodes on a pay-per-view basis.
The show will probably not be available on Hulu or Netflix at any time in the near future.
I'm an amazon prime member and I have a PS3/TV setup so I can stream it on my TV in beautiful HD.
If you're watching it via amazon prime, new episodes are made available every Friday. The main benefit is that you get to watch it commercial free...YAY!
