YouTube announced Monday that it is continuing to ramp up its rental titles, adding more than 600 movies to its list of available rentals.

Titles include films such as “West Side Story,” “Moonstruck,” “The Terminator,” “Robocop,” “Rain Man” and “Rocky,” according to a company blog post from Jonathan Zepp, the manager of TV and film content partnerships.

The films are available not only on YouTube but also on Google’s tablet and smartphone marketplace, Google Play.

The company also recently announced its partnership with Paramount, which added around 500 titles to the online store. The content partnerships are part of an aggressive strategy to compete with content stores such as Apple’s iTunes store and Amazon’s Prime marketplace, which offer thousands of titles for mobile devices. Google has deals with five of the six major studios — excluding 20th Century Fox — and at least 10 independent studios, including Miramax.

According to the post, the MGM titles will be added “in the weeks ahead,” though several are available for rent starting Monday.
