SYRACUSE -- The "shared services agreement" that brought CBS5 (WTVH) under the same roof as NBC3 (WSTM-TV) and CW6 (WSTQ-LP) could be ending in 2017. Sinclair Broadcast Group, which recently closed on its purchase of former WSTM/WSTQ parent Barrington Broadcasting, says it's not interested in renewing the deal Barrington had with WTVH's owner.
