While I was in the US recently, I was surprised by a billboard I saw, that was overlooking Canal Street in New Orleans. It was advertising a company whose entire business was built around selling APIs. Tech advertising in the US is always interesting - I've saw ads on TV discussing IoT three or four years ago and when you drive through parts of California advertising for tech companies is common.

But the move towards APIs is fascinating as it signals a major change in how software development happens and what the next generation of applications will bring.
