Are children exploited in the media?

So the BBC got in trouble this week for using a child actor in a role that involved sexual language and extreme violence/ torture.  Do you think many channels exploit children in their programmes?  What about the children that appear on Britain's Got Talent?  Is it ok if it is REAL children showing off REAL talents even though it can often be just as traumatising for them as they get upset / humiliated etc..
