The CBS and Fox stations in New York City are teaming up to share aerial coverage. Effective today, WCBS and WNYW have entered into an agreement to share a helicopter in the nation’s top DMA, TVSpy has confirmed.

WNYW was previously part of a helicopter sharing agreement with WNBC, the NBC O&O. Fox and NBC ended their New York agreement, and a similar one with their respective stations in Los Angeles, earlier this year. WNBC and KNBC now have their own choppers.

WCBS ended a helicopter-sharing agreement with WPIX, the CW affiliate, earlier this year. Costs associated with news choppers run a station approximately $1 million per year.
