Oak Hill Capital Partners is putting the Local TV station group up for sale, according to Broadcasting & Cable.

Local TV owns or operates 21 stations, including WDAF in Kansas City, KDVR-KWGN in Denver, WJW in Cleveland and KTVI-KPLR in St. Louis. B&C reports staffers are being alerted to the sale and instructed “to go about their business as usual” until the process is completed, which may take up to a year.
