TEMECULA, Calif. (AP) ¿ Outdoor Channel Holdings Inc. said Wednesday that it's laying off a quarter of employees at recently acquired Winnercomm Inc. because the economic downturn has hurt business. The owner of the Outdoor Channel cable network bought sports programming producer Winnercomm in January. Outdoor Channel did not disclose how many workers will be laid off and calls to the company were not immediately returned. According to CapitalIQ, Winnercomm has about 160 employees. Winnercomm owns the patented Skycam and Cablecam systems, which use aerial cameras to capture overhead video of football games and other major events. Winnercomm, based in Tulsa, Okla., supplies more than 1,000 hours of programming a year to 14 national television networks, including ESPN. Shares of Outdoor Channel, based in Temecula, Calif., rose 7 cents to close at $6.50 on Wednesday.
