The last logo used by WPWR before moving to channel 50.
WPWR moved from channel 60 to channel 50 in 1987.
Following the announcement of the shutdown of UPN (whose programming would be merged with The WB to form The CW), all Fox-owned UPN stations, including WPWR-TV, dropped all UPN references from their on-air branding. WPWR changed its branding to "Power 50 Chicago" (in reference to the station callsign), and adopted a new logo.
WPWR-TV affiliated with the CW on September 1, 2016, but continues to air MyNetworkTV programming.
