Amazon’s Prime Instant Watch service may not be overthrowing Netflix here in North America anytime soon, but across the pond their LOVEFiLM service has reached a milestone two million subscribers. The service which offers streaming video as well as DVD, Blu-ray, and video game disc rentals had a strong fourth quarter in 2011, the fast growing quarter since 2009. LOVEFiLM is also now offering a streaming-only service (just like Netflix), for an intro price of GBP4.99 per month. Check out the LOVEFiLM website if you want at http://www.lovefilm.com — but unless you’ve got a UK address you won’t be able to sign up for free trial. Note to Amazon: Why not drop the Prime Instant Watch service and open up LOVEFiLM in the U.S.? Well, maybe it’s not as easy as it sounds.
