If a show is over promoted, there is more possibility to lose audience.
My mom who is a typical neutral viewer and want to her extratime with Tv shows, even betweenher kitchen work, get irritated if she continuously watch the promos and always complained for the same.
After I read the reactions of people here about the over promotion of shows, I confirmed that the over promotion got irritated as whenever switch to tv viewers have to suffer the same stuff continuously.
So I do not want over promotion of MB
