1stly i do not agree with ur viewpoint as if sports broadcasters r earning money by airing such local leagues then it is good for their financial situation as normally sports broadcast business is too much costly to operate in and 2ndly these leagues too promote talent from regional level which includes small towns + villages and if it gets shown on major / leading sports channels then it further boosts confidence of players / staff part of these leagues.
Buddy,,Lastly it is not just Star Sports but Eirosport, Sports18 and Sony Sports too air such tournaments so please don't single out Star India while stating ur opinion
