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 station; it was kept during the station's early months as a CBS affiliate.
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.
