Ever discovered a cool video recommended to you by YouTube? Rebecca Tickle explains how music and video apps can recommend music and films you might like to watch next.

• Can you think of any other ways for a computer to recommend films you might like?
• Have you ever recommended a song or film to a friend? Why did you recommend it to them, and did they like it?
