Since WFLA was practically Media General's first station, most Tampa Bay residents will oppose the merger, because this is one of Media General's flagships stations along with WRIC-TV in MG's hometown of Richmond, VA. Also, News Channel 8 will have to make a new unrecognizable website name, like all Nexstar stations.
As a former Media General employee, I can assure you most Tampa Bay residents have no idea who or what Media General is, nor will they gather torches and pitchforks to oppose the merger. It won't even register.
NewsChannel 8, on the other hand, has had excellent local name recognition for more than 20 years. The new owners would be out of their minds to rebrand the station. That said, dumber things have happened.
I cannot imagine the iconic call letters will go anywhere. Remember how desperately Channel 8 worked to get them back around 35 years ago, when it changed to WXFL?
[For the uninitiated: Until 1983, Media General owned a TV station (Channel 8), radio properties (WFLA-AM and -FM) and a newspaper (the Tampa Tribune) in this market. Because of federal regulations, the FCC forced Media General to divest the radio stations. Since the radio stations were assigned the call letters three decades before the TV station was born, it got the right to keep them and Channel 8 had to change its calls. The TV station spent the next six years trying to reclaim its identity — even as other TV stations in the state tried to get them because of their value and recognition. From what I understand, Channel 8 ended up providing cash and services (like weather reports and marketing) to the radio station to "lease" them back in 1989.]
WFLA's website, on the other hand, could stand some improvement ... but I can't imagine the new owners coming up with a better URL than what already exists, unless it's newschannel8.com. Interestingly, that URL currently goes to a station in Connecticut that is owned by LIN Television, which merged with Media General in 2014. Of course, that certainly could change.
As an aside, there was a plan, circa 2000, to make TBO.com the combined multimedia platform for the newspaper and the TV station — bringing tampatrib.com and wfla.com under one roof. That didn't really go over so well. One of the objections from the TV folks was losing the WFLA identity. That culture still exists — whether it's enough to keep the new bosses from making changes, well, that remains to be seen.
