I’ve heard this fact about email in a bunch of places so I’m going to note it here in case it becomes interesting to remember later.

In the late 1990s, the world fell in love with email. The world was a little late: Queen Elizabeth II had been sending email for decades. In 1976, just years after email was developed as a way for academics to send messages within universities, the queen sent her first email at an event celebrating the arrival of an early internet network in England—and beat most of the rest of the world to the punch by two decades.
