Did You Know That... The @ Symbol Became Part of Email Because One Engineer Needed to Separate Two Things?
In 1971, engineer Ray Tomlinson was experimenting with sending messages between computers on ARPANET.
He needed a simple way to identify who should receive a message and which computer they were using.
He chose the @ symbol because it was already on the keyboard but wasn't commonly used in people's names.
That small decision created the basic format we still recognize today:
name @ ๐๐จ๐ฆ๐ฉ๐ฎ๐ญ๐๐ซ.
The symbol had existed for centuries before email, but Tomlinson's choice gave it an entirely new life in the digital world.

Did You Know That... YouTube's First Video Was Just a Man Talking About Elephants?
On April 23, 2005, a short video was uploaded to a brand-new website called YouTube.
It was only around 18โ19 seconds long.
The video showed YouTube co-founder Jawed Karim standing at the San Diego Zoo in front of elephants.
There was no dramatic production.
No special effects.
No viral challenge.
Just a simple video about elephant trunks.
That completely ordinary clip became the first video ever uploaded to YouTube the beginning of a platform that would eventually transform how the world watches and creates video.

Did You Know That... The First ATM Didn't Use a Bank Card?
In 1967, Barclays installed what is generally recognized as the world's first ATM at its Enfield branch in London.
But it looked very different from today's machines.
Customers didn't insert a plastic debit card.
Instead, they used a special paper voucher and entered a PIN. If everything matched, the machine dispensed a ยฃ10 note.
That may sound primitive now, but the idea was revolutionary.
For the first time, people could access their money outside normal banking hours without waiting for a teller.
Today, ATMs are everywhere.
But the journey started with a machine that could basically give you one ยฃ10 note at a time.

Did You Know That... The First Digital Camera Was About the Size of a Toaster?
In 1975, Kodak engineer Steven Sasson built a prototype that changed photography forever.
It didn't use film.
Instead, it captured images electronically and stored them digitally.
The prototype was huge compared with today's cameras, weighed several kilograms, and produced only 10,000 pixels about 0.01 megapixels.
It took around 23 seconds to record a single black-and-white image.
At the time, digital photography seemed like a strange experiment.
But that experiment eventually led toward the digital cameras, smartphones and instant photos we use today.
The surprising part?
The technology that eventually replaced film was invented by a company famous for making film.
