Those complaints are then assessed against the Broadcasting Code to see if they need investigating further.
The code sets standards for television and radio shows and broadcasters have to follow these rules.
For example, Ofcom has strict rules on what can be screened on TV before the 9pm watershed.
If we find a programme has broken those rules, then it will be found in breach of that code.
Every fortnight we publish a Broadcast Bulletin which includes our latest complaints adjudications.
To learn more you can read our latest Broadcast Bulletin which is out today.
