One of the first projects I worked on at Bell Labs back in the day, was a replacement for IMTS called HCMTS, High Capacity Mobile Telephone Service, later renamed AMPS, the original analog cellular technology. I was 2 years old at the time (joke, I am old ;) What was interesting is that during the break up of the Bell System, no one wanted the technology because the marketing research estimated that something like 150,000 people nationally wanted it. But they asked the question the wrong way, people were thinking of it like the old expensive IMTS, not something you could hold in your hand. That came later. It reminded me a lot of Kodak letting digital photography go because the early versions were klunky, and they thought it would never take off. Classic story in tech.
