宛如現代 Netflix 的魔法燈籠
Magic lanterns were devices that let people watch images on a wall. A lantern would shine light on photo slides to make the pictures appear bigger. Then, everyone in the room could look at the large images. Although the first magic lantern was invented in the 1500s, few people bought them because they were too costly. During the 1800s, brilliant businesspeople came up with an idea. They began renting lanterns to customers for a few days. Families could then afford to use them.
