The industrial revolution was every bit a marketing revolution, because there was no point producing things in abundance if you couldn't create corresponding demand — and entrepreneurs like Watt and Boulton proved it by inventing the horsepower as a marketing unit and pricing steam engines as 'hardware as a service' in 1775.
Rory argues that great 'inventors' like Watt succeeded only when they changed behavior, not just machines. He recounts Watt inventing the 'horsepower' purely as a marketing metric so mine owners could calculate displaced horses, and Boulton & Watt pricing engines as hardware-as-a-service in 1775 — the same model Rolls-Royce later used for jet engines.

Rory Sutherland: my argument is that an invention isn't an innovation until it changes behavior... So, Watt went out and invented a unit we still use today, which is called the horsepower. And the reason it's not named after a famous scientist like the ohm or the Newton or the coulomb or the Watt for that matter or Celsius or anything of that kind is because it's a marketing unit. It was invented for marketing purposes... the industrial revolution was a marketing revolution every bit as much as it was an industrial revolution because there was no point in being able to produce things in abundance if you couldn't create corresponding demand... They said we'll supply it for free you pay us a third of the money that you save on coal. So it was literally hardware as a service. Bear in mind this was 1775. I mean years later Rolls-Royce started charging airlines for jet engines in the same way effectively.
