Good morning, everyone. Today we're going to look at the history of the postal service. Many people assume that the first stamps were introduced in the UK in 1840, and that's true. However, the world's first adhesive stamp, the Penny Black, was actually a British invention. But interestingly, the idea of prepaying postage came from a schoolteacher named Rowland Hill. He proposed that the sender, not the receiver, should pay for the mail. This change made the system more efficient and affordable, and it was quickly adopted by other countries.
