The funny thing about media consolidation is that it nationalizes everything. I hear a lot about Eric Adams, the mayor of NYC, and Karen Bass, the mayor of LA, but very little about the cities and towns that are within 20 miles of me. The local Nexstar newscast is usually only telling local stories about for the first 6 or 8 minutes of the show.Getting local governmental officials involved could be helpful, too: it's easy to point them to what happened to newspapers and the resulting loss of local news coverage and let them draw the logical conclusion that this would happen in TV, too. That's not to mention competing business interests.
That's not even close to accurate. The Reagan-era FCC loosened the national ownership rules from 7-7-7 (enacted by the Eisenhower administration) to 12-12-12 in 1984. https://www.nytimes.com/1984/07/27/business/fcc-raises-limit-on-total-stations-under-one-owner.html"Newsmax noted that President Ronald Reagan instituted the cap to block liberal networks like CBS, NBC, and ABC from owning local market stations across the nation". I didn't think it had anything to do with "liberal networks" since there were no "conservative networks". .
The 39% rule that prevents e.g. ABC/Disney from owning a station in each market wasn't created until President Bush signed the Consolidated Appropriations Act of 2004 and the FCC created regulations enacting the specifics. https://docs.fcc.gov/public/attachments/FCC-06-117A1.pdf
