Should TV Adverts have age restrictions/ratings?

In my honest opinion i would advise that TV adverts should not have age ratings as the audience are not going to bother standing up and leaving the room if the age is not applicable.Furthermore by having age restrictions this will then force the people to change the channel,this decreases the demand for the product the company is sell.

On the other hand, a reason as to why age restrictions should be applied is because some adverts contain sexual scenes that may be to explicit for those bellow the age of 16, therefore age restrictions would be applicable at this point also. Moreover,some of the other reasons as to why age restrictions should be applied to TV Adverts is because some have very bad language which may harm those or influence those that are still at the early ages of there life. 

Overall i believe that the the argument against age restrictions is favored because people do not have time to change the channel when something explicit comes up which may harm the younger viewers.
