More trivia. When WSIX moved to channel 2 the letters changed to WNGE, which stood for Nashville General Electric, who owned them at the time. That's when the engineers became the only union shop in town for local tv, since GE is heavy union labor.
The current letters WKRN were for the next owner, Knight Ridder Nashville.
Neither of those well financed companies could get a dent against National Life or Life & Casualty loyalty for channel 4 & 5. Somehow a fleding operator named Vince Young thought he was smarter than all of them and bought WKRN. I'm not sure if they're still in bankruptcy with Young Broadcasting still owning them but it's a common story. Everybody in broadcasting thinks he can do it better than the current owner and some go broke or at least loosing value, just to prove they're right.
