AOL, TW ANSWER FCC REQUEST

In a 50-page response to the FCC's request for information, the two companies defended AOL's efforts to keep its Instant Messenger system closed to users of competing services.

AOL reiterated its stance that it backs an open worldwide instant-messaging system, but only if it protects users' security and privacy. Instant messaging allows users to send notes that instantly pop up on the receiver's screen.

The companies stated that people could avoid barriers between different instant-messaging services by subscribing to more than one service. But they also said that any system requiring users to manage multiple passwords and IDs is "seriously flawed."

Also in the response, Time Warner said it may take advantage of AOL TV's arrangements with set-top box manufacturers to accelerate the rollout of its digital-cable service, which has been slowed by a shortage of such devices.

The FCC's request was part of its review of the companies' proposed $109.33 billion merger.
