Actually an automobile did require a lot of PR to convince people it was better than horses. You just live in a world where everyone uses automobiles already.

If it wasn't for PR people then we wouldn't be engineers working on computers today. People initially didn't like computers either.

In both cases it wasn't immediately obvious why people would want to use these products.

I'm curious as to what you developed that was so immediately obvious to customers that you didn't need a sales team to become so wealthy and popular.
