MUMBAI: When it comes to India's favourite pass time, nothing comes close to Bollywood.

The growing user base of YouTube in India has driven movie producers/distributors to the platform to test the waters, and get instant reactions on the movie's potential success at the Box Office.

With over a billion users worldwide, Indian movie trailers are enjoyed by a global audience, but what matters the most to the producers is the viewership and popularity of trailers in India. In the list of the top 10 movie trailers viewed in India from October to December 2014, the trailer of PK rules the charts.

Interestingly, horror has also emerged to be one of the most consumed genre when it comes to movie trailers with the trailer of Alone bagging the third position on the chart. Khamoshiyan, MSG, and Dolly ki Doli were also among the others that grabbed a place in the list of most watched trailers.
