does more local contents draw more viewers?

Read an article from a newspaper that more local contents will draw more viewerships. While having more local content is good as in local productions are getting some demands. To draw viewers would be hardly convincing. First the usual point here is that, there is only one TV broadcaster here. The contents just doesn't change much as compare to the few years when there was a competitor. You have a good stable of artists yet it is always the same few of them so call brighter stars. The storyline of the shows are the usual or copying those HK dramas. variety contents and those singing or talent contest are flooding the timeslot. Viewers simpy have no where to switch to unlike some with pay TV. I don't see how it increase when there is no other choice at all.
