Aamir Khan has always managed to stand apart from any crowd. This time he has decided to not promote his film on TV at all when everyone else have been appearing on all shows possible to get their films get noticed.
Shahrukh Khan, for instance had done extensive promotions on a number of shows and the success of his film Chennai Express is a good example to show the benefit. Every movie that has been released have made it a ritual to appear on all popular shows in an attempt to get maximum exposure.
Aamir Khan on the other hand has said that he will be leaving this work to the trailers on his film Dhoom 3. Does this mean he will not even be appearing on his best friend in the industry Salman Khan's show Bigg Boss too or not, only time will tell. With Salman Khan sporting Aamir's Dhoom 3 hat on Bigg Boss 7 gave an impression that Aamir will be coming onto the show very soon.
Also, though the actual promotion of any film is supposed to be done with their trailers, it is also extremely important to promote their films in as many platforms as one can, at least when they have invested Crores in making the film.
