In an interesting turn of events the Google owned YouTube are going to experiment with renting films though their online video playing service.
Before people in the UK get too excited there are a couple of things you should now, first of all its for the US market only (at the moment), so we can stop here, next there are no blockbusters at the moment, in fact there are just 5 films, all from this years and last years Sundance Film festival.
You will have to pay for the movies via Google checkout, not a real hassle but if you haven't set it up yet then you have to go through that whole process as well, but once done your all set.
For people in the US the rentals will be available from tomorrow (22nd January 2010) and once you have bought a film you have 48 hours to watch it.
This is an interesting move, and with new televisions announced at the recent CES that can connect to a wireless internet connection then this has potential, also in the UK there is an incentive as there is little in the way of on-line rental services at the moment.
