Our streaming world
Sit in front of a TV, computer or smartphone.You’ll find a world of entertainment. Choose from thousands of TV shows and films. Play realistic video games. Watch a live concertor football match. Chat with kids in other countries. You can even jump between these media in seconds!
It wasn’t always like this. At one time, the BBC was the only channel. Then in 1955, ITV began broadcasting. People could only watch what a station was playing at that moment. The first web pages only had text and maybe a photo or two. At the dawn of the internet, people sometimes waited hours to get a file.
Early video games were very simple too. In Pong, two players sent a digital ball back and forth across a dotted line. It was a digital version of ping-pong. And it was a huge hit. People had never seen anything like it.

CHAPTER 1 What is streaming?
When people speak, they send out sound waves. These waves hold information. The listeners’ ears take in the waves. Their brains work out what the sound waves mean.
The internet works in a similar way. Information travels to an electronic device. This information could include texts, pictures, sounds or all of these. It may travel through wires, as radio waves, or as a satellite signal. It might reach a T V, phone or computer. That device shows the information. Streaming uses the internet to send information, just as speaking sends information through sound waves.
