Summary Box: Game service OnLive coming to tablets

COMING TO A MOBILE DEVICE NEAR YOU: OnLive, a startup whose technology streams high-end video games over an Internet connection, is expanding its service.

WHAT IT IS: The company’s streaming technology is similar to what Netflix Inc. and others use to let people watch movies online. However, OnLive has yet to reach a mass-market audience.

NOW AND THEN: Users could already stream games using OnLive’s “microconsole,” a cassette-tape sized gadget attached to their TV sets, or on computers. With the update, users will be able to play console-quality games on tablet computers and smartphones using an application.
