the people on Sa Re Ga Ma Pa...some people did have it, but some didnt. and its a shame to see that quite a few of them who didnt originally have the x factor, tried to produce one for themselves...some people were succesful, some werent... i dont think it'll be advisable for me to list out the names of these people.
and as far as "does the x factor sell in the market" YES. YES YES YES... i'm not sure about talent shows, because people vote on maaaany different categories, but say newcomers in the film industry, especially for th girls, they let the camera shoot the most vulgar pics/sketches of themselves, let these get posted everywhere, let the public see, and let the public make them the headline...this x factor thing is everywhere
