WOIO was first launched on May 19, 1985. It became one of the original charter Fox affiliates on October 9, 1986; that was changed later in 1994 when WOIO switched network affiliations from Fox to CBS; this sent the area's Fox affiliation to former CBS affiliate WJW; this logo survived the affiliation switch, and is one of a few TV station logos that render its channel number as a word, and not a number as is custom. This was the also the only logo used by the station as both an independent and Fox staton.
This logo along with the WUAB logo of the same period continued to be used on the station's Doppler radar tower on I-71 in Brunswick until it was demolished in late 2015–early 2016.
On August 24, 2015, WOIO rebranded as "Cleveland 19".
On April 8, 2019, Cleveland 19 rebranded as CBS 19.
