Looking at PBS affiliate websites: at the time Sen. Edwards was five or six years old, what was to become SCETV was just organizing and appeared to be a closed circuit educational network.

Another nearby PBS station (WTVI) from Charlotte, NC did not even exist.

The local NBC affiliate did not exist.

Neither did the ABC affiliate (WOLO). He was eight years old though when the station launched.

A CBS affiliate did exist, however. (WSPA)

So did another affiliate (then WNOK, now WLTX)

The NBC affiliate (WFBC/WYFF) did exist.
I appologize for the error.
