WBSF

With the merger of The WB and UPN to become The CW, WBSF became the area's network affiliate in September 2006 when the channel began broadcasting over the air.[3] Because of this, a chance existed that WKBD (which along with WBKP are the only other over-the-air CW affiliates in Michigan) would be dropped from this market's cable systems as both WBSF and WKBD would be CW affiliates. However, in the case of Midland, two CBS affiliates do coexist on the same cable system. This occurred on Charter's Tri-Cities systems which replaced WKBD with MyNetworkTV affiliate WNEM-DT2 that became the new home of Pistons basketball that year. As a result of the network change, WBSF rebranded from "Mid-Michigan's WB" to "CW 46 Mid-Michigan". However, its call letters were not changed as the "B" in the calls also stands for Bay City which is the station's city of license. "S" and "F" stand for Saginaw and Flint, respectively. WBSF signed-on its analog channel on September 13, 2006 although it continues to be seen on WEYI-DT2. As such, it is the only full-power television station to be built and signed-on by Barrington Broadcasting although Barrington acquired its construction permit from ACME Communications before construction began.

In June 2008, WBSF received its Construction permit for its digital facilities with the station switching from analog to digital broadcasting on June 12, 2009.[3]

On February 28, 2013, Barrington announced that it would sell its entire group, including WBSF and WEYI, to Sinclair Broadcast Group. However, due to FCC duopoly regulations, since Sinclair already owns Fox affiliate WSMH, Sinclair will transfer the license assets of WBSF to Cunningham Broadcasting and of WEYI to Howard Stirk Holdings (owned by conservative talk show host Armstrong Williams). WSMH will take over the operations of both WBSF and WEYI through local marketing agreements when the deal is completed.[4] The sale was completed on November 25.[5]
