I think there actually is a technical reason for this. I used to see
this problem a lot more back in the 80s and early 90s than I do now,
but there is a problem called "ingress," which, as the cable people
explained it to me, is that if the station is the carried on the same
cable channel as its air channel, the station's air signal conflicts
with its cable signal, causing diagonal lines across the picture. In
Brookline this seems particularly common on Channel 2.
Cablevision, which was Brookline's cable company at the time, didn't
want to move stations to other channels because of the confusion that
would cause, and over the years, they seem to have improved the
situation considerably, but I remember a lot of discussions about
that when I was on the town's Cable Monitoring Committee back then.
