WCSN was launched on March 24, 2007, as the Columbus Sports Network (CSN), Central Ohio's first and only continuous all-sports television station, broadcasting events, features, highlights and news on professional, collegiate, scholastic and amateur sports teams in the area.
While under the ownership of United Media Acquisitions and prior to ceasing local original programming, WCSN was carried on cable television systems in the market; Insight Communications had it on Channels 78 and 524, and WOW!
On June 6, 2008, The Columbus Dispatch reported that the production of programming had ended and that the business model was being reviewed.
By August 10, 2009, it broadcast only a notice that it had "video trouble" and that "this channel is temporarily off-line due to technical difficulties".
In 2009 the original owners, United Media Acquisitions, filed for bankruptcy protection and the station was sold to Columbus Television, LLC.
