Netflix is a DVD rental service that's run entirely on the Internet. Each user gets his or her own queue for movies to rent, and the service will ship out up to four at a time via postal mail. The service doubles as a review network, as each user also can review movies they've seen and view other community members' takes too. Users also can give movies a thumbs up or thumbs down to receive suggestions for future rentals, based on what other users have rented.
Netflix has achieved its popularity for its low-priced rentals and lack of late fees. Recently, Netflix launched a service that lets users stream entire movies on their computers.
