The first TV was made by John Baird in 1925. It had one color. It could only show 30 lines. This was just enough room for a face. It didn’t work well, but it was a start.

1. It was in New York- Few people had TVs. The broadcasts were not meant to be watched. They showed a Felix the Cat doll for two hours a day. The doll spun around on a record player. They were experimenting. It took many years to get it right.

By the end of the 1930s, TVs were working well. America got its first taste at the 1939 Worlds Fair. 2. There were 200 small, black and white TVs set up around the fair. The U. S. President gave a speech over the TVs. The TVs were only five inches big but the people loved it.

By 1948 there were 4 big TV networks in America. They aired their shows from 8 to 11 each night. Local shows were aired at other times. 3. TV was not "always on" like it is now.

Color TVs came out in 1953. 4. Also, shows were aired in black and white. By 1965, color TVs were cheaper. TV stations started airing shows in color. People had to switch if they wanted to see the shows.

Now most TVs are high-def (高清). This means that they have many lines on them. 5. TVs have come a long way since Baird’s 30 line set. High-def TVs have 1080 lines. There are state of the art sets called 4K TVs. These TVs have 3,840 lines. Some people watch TV in 3D. I wonder what they will come up with next.

A. This makes the image clearer.

D. The first TV station was set up in 1928.
