Bit more info on Apple TVApple Inc.’s lofty plans to build an online television service are coming into sharper focus. The technology giant is in talks with programmers to offer a slimmed-down bundle of TV networks this fall, according to people familiar with the matter. The service would have about 25 channels, anchored by broadcasters such as ABC, CBS and Fox and would be available on Apple devices such as the Apple TV, they said. Some media executives said they believed Apple was aiming to price the service at about $30 to $40 a month. The company is aiming to announce its new service in June and launch it in September, according to people familiar with the matter. The service would work across all devices powered by Apple’s iOS operating system, including iPhones, iPads and Apple TV set-top boxes.
