Diffusion of Innovations Theory
I think one of the most major innovations that was heavily subject to the Diffusion of Innovations Theory was the mobile phone. Initially, "mobile" phones were connected to cars and costed a lot of money. However, in 1973, Motorola released the first truly mobile phone prototype. The prototype, and the consumer models based on it, that came out a whole 10 years later, in 1983, had 30-minute call time but a 10 hour charge time. Even with these specifications, there were many early adopters, with people on wait-lists for the “mobile” phones.

Eventually, as with virtually all technologies, cell phones became smaller, more affordable, and overall better. I would say that the early majority and late adopters for cell phones are kind of blurred together. It's quite obvious why cell phones caught on, the abili...
