The BBC is a really old company that started in England in 1922. It's like a big TV and radio station that makes lots of different shows for people to watch and listen to.
When the BBC started, it only had one radio station and it only broadcasted for a few hours every day. But as time went on, more and more people started listening to the radio, so the BBC made more radio stations for different types of music and shows.
In the 1950s, TV started to become popular and the BBC started making TV shows too. At first, there was only one TV channel and it only broadcasted for a few hours each day. But soon, more TV channels were added and they started to make more shows for people to watch.
As time went on, the BBC continued to make more and more shows for people to watch and listen to. They made news shows, cooking shows, game shows, and lots of other types of shows too!
Now, the BBC has lots of TV and radio stations and they broadcast shows all over the world. They also have a website where you can watch and listen to shows on your computer or phone. And that's the timeline of the BBC!
