This Friday a pilot scheme to add age ratings to online music videos starts but don't expect to see any huge 12s, 15s or 18s on videos just yet.
All parties involved say people watching the videos won't see any changes until the end of the year.
YouTube says it is committed but technical change may take time and Vevo has agreed to trial the scheme.
Three of the biggest labels in the UK - Sony, Universal, and Warner Brothers - have all also agreed to take part.
But it will only apply to artists signed to UK labels.

In August, David Cameron announced the pilot saying that he wanted "to help parents protect their children from some of the graphic content in online music videos".
The British Board of Film Classification (BBFC), the same body which rates films and DVDs, will be deciding which videos warrant an age rating.
