If you have ever lived in or visited large markets, the FOX affiliates there usually have complete newsrooms and commit probably 4-6 hours of their time to live news coverage. In little old Richmond, that's not the case. WLRH (Sinclair-owned FOX) has had WWBT (Gray-owned NBC) contracted out to do their 10 pm news. I believe at some point in history the FCC required all over the air stations to produce 1 hour of news coverage daily to keep their signal.

Somewhat related, WUPV / Richmond's CW affiliate used to do a broadcast of local news. Gray owns that affiliate and the WWBT newsroom produced that as well. Not really related, it will be interesting to see what happens with the CW in the future. Nexstar, the company that owns WRIC (Richmond's ABC), owns what used to be WGN-America and is now Newsnation Prime. They own a large number of CW affiliates and bought a majority stake in the CW company recently as well. I imagine they will attempt to buy the WUPV from Gray at some point if they change materially change what programs the CW.

I have not watched more than 5 consecutive minutes of local broadcast news in a decade but my mind is a prison for useless knowledge.
