It was (and still is) fairly quiet, but there were also Litton Engineering Group [1] and The Grass Valley Group [2] in the area. There are still a surprising number of engineers in the area due to the large number of high-end and broadcast video companies still in business. I think AJA is the biggest but there is also Sierra Video and Renegade Labs. Grass Valley is still here as well but it has changed hands a few times over the past few decades.
