WGN-TV

1993–2002


The "9" (which looks like the Japanese hiragana character for "no") in the 1993-2002 logo is also turned upside-down into a "G" in the black bar with the "WGN" callsign; this logo was used by the national superstation feed of WGN-TV in promos and IDs until 1998, when only the "WGN" portion of the logo began to be used on the superstation feed.

2017–present


An entirely new logo design for the station was introduced on May 17, 2017.
