1. Netflix - standard in online movie access, high video quality, discount rates
Netflix started life mailing out Videos to members, but now are the alpha male of online movie streaming in America. Netflix has a solid focus on providing a good streaming service and ensuring new content is regularly put into their online library of movies and TV shows. They understand the potential and major benefits movie streaming rentals and are market leaders in getting it to the front of the new movie revolution.
2. Blockbuster - Most likely too little and too late
Though Blockbuster in their current form isn't departed yet, very few expect them to live on for much more time. They are producing a major effort to join the online movie streaming get together, but just like Netflix are yet to provide HD titles. It is difficult to say what's going to become of Blockbuster, their emphasis remains on the physical media, but their online catalogue of streamed content is growing weekly.
3. VUDU - Opportunity to obtain the newest releases in high definition
VUDU is aimed more at occasional movie viewers than those who want to undertake regular movie marathons. The appeal with VUDU is that you only pay for what you see and there is no contract tying you into their service.
4. Hulu Plus - View your favorite television shows when you wish
Another online movie streaming site that has been established for a while is Hulu, who made their name streaming re-runs of good old TV programs. Hulu is somewhat unlike any other services in that their focus is a lot more on television programming.
If you sign up for Hulu you're subscribing more for the library of television shows than anything else. It's the ideal service for people who want to watch several hours of old TV re-runs regularly. It can work great together with VUDU to provide you with a good selection of viewing options without having to pay for satellite tv.
5. Amazon Prime Streaming - a bit more costly compared to the others but maybe worth a go for frequent Amazon customers
The Amazon Prime service provides you with free shipping on purchases, access to movie streaming and other discounts too. Add that charge onto the cost of $4+ a movie and you may well be better renting Blu-rays or going to the movie house.
Bearing that in mind, you can still find free movies and TV shows available, that are older and in all probability ones you've viewed several times over on your local TV stations. Additionally they provide a free trial for 1 month, so you can always test it out and if you’re dissatisfied within 30 days, just cancel.
