There are many options when viewing streaming videos of movies or television shows. While one source may have certain content, the other source, more than likely, will not have the same available. The provider of my choice is Netflix.
Netflix allows for quick use and is very user friendly. Netflix is available on multiple devices. So if I am stuck at an airport or in a car, I can use my phone, tablet or other mobile device. Netflix is of course available from a computer, but also places like Apple TV.
Now of course Netflix has competitors. One of the biggest is Hulu. I have accounts with both. However, Netflix is commercial free. No interruptions. Hulu has commercials. This has been my main drawing point to Netflix. I pay to not have commercials. I want the freedom and ability to start and stop what I am watching. My time is limited and Netflix understands that.
