Celebrities in India are defined by two verticals,Cricket and Bollywood.Though Bollywood is somewhat tarnished with links to Mafia, cricket atleast has a comparatively clean image(Match fixing not withstanding).So, for an influential celebrity, my vote goes to Sachin Tendulkar.<p>p.s:Maybe in India, we should have two new degrees, MBA and MCA, Master of Bollywood Administration and Master of Cricket Administration where they teach you on how to monetize and build businesses out of these two :)
