So yeah I don’t know if Warner is the same thing as Time Warner, but if that’s the case, Medford, MA is now serviced by Comcast so I’m not sure when that would have been, but I’m guessing this is from the early 80s. I’m surprised that they had pretty much every single broadcast channel in the region, and even back then they had all 4 PBS stations, but no MTV or even HBO.
