To me the missing link is Bose. (If it was a gateway product) How they sold 10s of millions of units. I honestly don't know how, because I never had any itch to buy their products. But they sold to people rich and poor it played music and made them feel special and they enjoyed (I think) the music
Can anyone replicate it today? Alexa?
An important fact is that most people who own something that plays music don't use it. Other than at Christmas.
