Q. How important are regulations on TV advertising? 
Umm … I think regulations on TV advertisements are important. Most of the 
advertisements are aired during the middle of programmes and news. It is 
highly irritating. The regulations should take of the issues. Besides, the 
regulations should direct the TV stations to air advertisements during specific 
hours. It happens that the TV stations air the advertisements around the day 
and they do not have any specific schedule for the airing. It appears that they 
air the ads based on their will. So, I think the regulations on TV advertising are 
highly important.
