There have been many vulgar interviews in the history of the world. But this depends on the policy of each channel and organization conducting interview to whether allow it to go on air or not. Pakistan is a type of country who has been very strict in airing controversial content on the air.
It is due to the fact that PEMRA has done a lot of efforts in improving the content quality. It has banned many channels and suspended the licenses of many others as well. So the quality of the content is getting improved day by day. The graphic content gets blurred while airing now which was lacking before.
