March 16 (Reuters) - Apple Inc is in talks with programmers to offer a slimmed-down bundle of TV networks this fall, the Wall Street Journal reported, citing people familiar with the matter.

The service would have about 25 channels, anchored by broadcasters such as ABC, CBS and Fox, and be available across all devices powered by Apple's iOS operating system, including iPhones, iPads and Apple TV set-top boxes, the newspaper said.

Apple has been talking to Walt Disney Co, CBS Corp , and Twenty-First Century Fox Inc and other media companies to offer a "skinny" bundle with well-known channels like CBS, ESPN and FX, leaving out the many smaller networks in the standard cable TV package, the Journal said.

The service is expected to be launched in September. (http://on.wsj.com/1GOgcrv)

The talks do not involve NBCUniversal, owner of the NBC broadcast network and cable channels like USA and Bravo, because of a falling-out between Apple and NBCUniversal parent company Comcast Corp, the newspaper said.

Apple and Comcast were in early-stage discussions last year to offer a streaming-television service that would allow Apple set-top boxes to bypass congestion on the web.

Apple spokesman Tom Neumayr said the company does not comment on rumor and speculation. Reuters could not immediately reach Disney, CBS, and 21st Century Fox for comment outside regular U.S. business hours.
