I took it to be the "norm" in Bangladesh/the Indian subcontinent. Perhaps no broadcast guidelines exist like they do in the US as proscribed by FCC, and similar authorities in other countries in the west. I know Film Censor Boards exist in those countries, but are broadcast television in their purview?
In the end, I expect the general notion of "decency" is predicated by cultural context. Graphic scenes of violence or its aftermath could be easily tolerated whereas a kissing scene or that of a woman in bikini would not be.
