At Wharton I interviewed the founder of Jerrold electronics. Iirc (this was a long long time ago) his Philadelphia connection to Ralph Roberts (comcast) was how he built Jerrold (they made cable boxes). Comcast of course grew large by starting and getting it's first cable franchise in a small town in Mississippi. Nobody chooses their cable company the cable company chooses you. (I actually have an audio tape of that interview that I made.)
