The CW and MyNetworkTV first appeared in Eureka respectively on KUVU-LP (channel 9) and KEMY-LP (channel 33), both analog-only stations and the latter a semi-satellite of
KRVU-LP in Redding, as part of the Eureka Broadcast Group, which owned
CBS affiliate
KVIQ and several other stations with affiliations to
Fox,
UPN,
The WB and others. KUVU and KEMY were dissolved in 2014 and Bonten Media Group, who had purchased most of the Eureka Broadcast Group stations including KUVU and KEMY in 2012, launched KECA as a digital replacement for the two defunct stations in the Eureka market. On April 21, 2017,
Sinclair Broadcast Group purchased KECA as part of a four-station deal. The sale was completed September 1. In June 2020, Sinclair upgraded the station's facilities to
HD. == Subchannels ==
