It is the first ad by Aamir after he became the company's brand ambassador. It will go on air from Monday.
'We are proud to have Aamir working on the ad and happy with the outcome of the final product. No other actor could have done the same so effectively,' Vikram Mehra, chief marketing officer, Tata Sky, told IANS.
