all reality shows are commercial based buddy....
all the thing they need is to get more money, previously they depends on some kind of serials, movie based programs like that..now reality shows, in future who knows.....
their bottom line is to make the money .They will do anything for that, Nobody is gonna resist that.....
There is no reality at all in these reality shows. Every thing is based on script based and for the sake of name/fame and money. Many fools among the general public are getting attracted to this new trend of programs.
