300 years ago, there was chaos on the seas.
There was no âprime meridianâ â no agreed longitudinal (eastâwest) reference point for sailors to calculate position and time.
France used Paris; Spain used CĂĄdiz; Italy used Naples.
This created confusion, inconsistency, and risk for navigation and trade.
That began to change in 1767, when the British Royal Observatory did something that would change the course of time.
It published the Nautical Almanac, making its astronomical tables widely available.
Ship owners, traders and navigators loved it.
No more guesswork and no need to build their own calculations from scratch.
And a curious thing happened.
Because the data came from one place, users implicitly adopted that place as their reference point.
The Observatoryâs meridian became the default.
Where was it?
Greenwich.
By the early 1800s, this standard was already dominant at sea. By the 1840s, British railways adopted Greenwich Mean Time to solve their own coordination problems. And by 1884, the world made it official: Greenwich was the world's prime meridian.
The interesting thing is that Greenwich didnât become the global standard because it was mandated.
It became our marker of time because it was useful, accessible, and easy to adopt.
Weâve seen this happen more recently, too.
Google didnât start as a monopoly. It became the default by offering tools that were free, easy and useful.
And right now, weâre watching the same dynamic play out again.
The race in AI isnât just about who has the best model, itâs about who solves a problem in the most accessible way.
That's who will become the new modern âmeridianâ.
