trailer. The first teaser trailer was released digitally on 9 September 2013, coinciding with Ganesh Chaturthi to mixed response; while fans of Rajinikanth were satisfied, others criticised it for its "poor visual effects". It was also noted for its similarities to the teaser trailer of Soundarya's shelved animation venture Sultan the Warrior, that was also supposed to feature Rajinikanth. Nevertheless, it was viewed over 1 million times on a single day, establishing it as one of the most anticipated film teasers in the history of Tamil cinema. Soundarya also announced that a second trailer would be released, which would feature Padukone prominently, and unlike the first trailer, it would have sound and dialogues. The trailer was released in Tamil, Telugu and Hindi on 9 March 2014, the same day of the audio launch. In 2012, the producers struck a deal with Karbonn Mobiles, an Indian telecommunication firm that will involve Kochadaiiyaan merchandise worth with screen savers and images from the film along with the trailer, behind the scenes shots, the signature tune of the film and lead actor's signature on the back cover of phones. However, delays in the film caused the clause to be modified. Sudhir Hasija, chairman of Karbonn, said, "We will roll out a million handsets by February-end or first week of March 2014 with a pre-loaded app for the movie. All the handsets will come with the signature of Rajinikanth. This is the first time any mobile handset maker is launching products with an augmented reality app." The promotional tactic is an extension of Eros' alliance with Karbonn, wherein the latter will make a million special-edition phones. A company called InGage Technologies have done its complete development. Using augmented reality, they set interactive Kochadaiiyaan hoardings in association with Karbonn Mobiles. Eros has deployed 500 interactive hoardings across India. People will have to stand in front of the hoarding and send an SMS to activate the hoarding. Karbonn stated that an estimate of 400 hoardings would be put up across the country, majority in southern states of India. Hoardings and banners of the film will be displayed at 3,650 Bharat Petroleum stations across South India. On 21 April 2013, Soundarya revealed a first fully 3D rendered picture, which shows Rajinikanth in two different avatars. It was also announced that a "making-of-the-movie" video would be released, where a song featuring Rajinikanth's voice would be used. It was shown
