YouTube has announced that they will be getting rid of the 30 second ads you cant skip.
Adverts are a big part of how YouTube and video owners make money. The more views the adverts get, the more money the advertisers pay.
YouTube gives you the option to skip the ad after five seconds, but this is not always the case. Sometimes you might have to watch a full 30-second ad before being able to access the video you want.
However, the feedback on the 30 second ads showed that often people stopped watching the video because of the long ad.
Shorter ads will still be on YouTube to enable them to make money.
