Earlier the Duke and Duchess of Cambridge formally registered the birth of their son, Prince George.
Prince William did the honours, signing the birth register entry for the third-in-line to the throne at Kensington Palace this morning.
Thanks to the power of modern media, we found out about it almost immediately.
But thanks to our friends at the Northamptonshire Film Archive Trust, we can show you some newsreel footage of a previous royal birth that shows it wasn't always like that. Phil Brewster reports.
