Good morning, class. Today we're going to discuss the history of the postal service. While many people think the first stamps were issued in Britain in 1840, in fact, a similar system was used earlier in Austria.

Interestingly, the idea of prepaying postage was introduced to solve a practical problem: in the early 19th century, many recipients refused to pay for letters they didn't want.
