I second @JackityJack's comments. People in the industry are watching WJZY closely. Nexstar is looking at all aspects of this station as they believe it was under performing due to poor allocation of resources under FOX. For example, FOX requires stations to execute a heavy quarterly marketing spend. This was evident early in WJZY's run as a FOX affiliate. They plastered the region with billboards and radio/cable commercials for their Fox News Carolinas Primetime, as it was then known, which was a trainwreck...as most products are at launch. Instead of quietly launching, working to find their voice, and THEN advertising, they spent heavily and drove curiosity viewing of a bad product. This put them in a hole that one could argue they are still working to climb out of. The list goes on, but that's just one concrete example.
As for talent departures, there's no drama. As contracts end, Nexstar is looking to put their own stamp on talent. While it is always sad when contracts aren't renewed, it comes with the territory. And when you are on a morning show that still scratches every now and then, it can't be a surprise that the new owners are looking to shake things up. None of this is evidence of FOX returning to Charlotte. It is just a new owner looking to invest in their new property. Whatever your personal opinion of Nexstar is, that's your choice. But people at rival stations and inside WJZY are watching with curiosity as Nexstar amps up the investment for the future.
