Blockbuster said Tuesday that it is teaming up with the online movie downloading service CinemaNow to offer more than 10,000 movies and TV shows for rent and sale. Users of the service, called Blockbuster Powered by CinemaNow, will be able to watch the videos over a variety of devices, including mobile phones and other wireless devices, including Apple's ubiquitous iPhone and iPod Touch, and TV sets, game devices, and Blu-ray disc players connected to the Internet. "Our goal is to offer consumers the most digital content, the most accessibility, via the most devices, both in and out of home," Blockbuster chief Jim Keyes said in a statement. The move comes on the heels of similar moves by Blockbuster's online rival Netflix, which already provides free streaming to its regular monthly subscribers. Blockbuster did not indicate how much its own service, which is expected to debut in the second half of the year, will cost.
