Generally people prefer to stay at home and watch their fav. actors on TV rather than standing in a long queue in front of cinema halls. Thats the reason small screen has got overwhelmed popularity in terms of entertainment. The tradition has started by Big B through KBC, one of the super hit shows ever produced on small screen. And actors believe that when audiences watch their movie, they remember them only till they watch their fav. actors on screen after that they tend to forget them. Whereas this is not the case with small screen. Where they can watch their acting closely and that made them remember their fav. actors for long time. Earlier it was not like that. There were limitations. Stars on big screen never thought of acting on small screens in those days. Today the situation is totally different.
