Amazon recently unveiled its Amazon Prime unlimited video streaming service, an offering that will compete with a similar service from Netflix. You can use Amazon's new unlimited streaming deal to watch more than 5,000 movies and TV shows on your Mac or Windows PC, as well as select set-top boxes and Internet-connected TVs.
