Totally agreed. I remember the first couple years of Chrome, and I didn't work at a tech company at the time, but everyone did work in front of a computer.

It was remarkable how quickly Chrome spread among the employees. Nothing to do with advertising -- just that it was so much faster and the whole app never crashed.

Whenever you heard someone cursing because their browser had crashed and they lost their tabs and immediate work, someone in the next cubicle would go, "why aren't you using Chrome?"

It really was that simple. It was all word of mouth.
