He revealed how everyone has been working on the set with safety precautions."This year is of course very different and challenging for all of us is every aspect. But it has been a year of learning and exploring avenues that probably weren't thought of, paving the path for something meaningful, leading us to the insight that there is a spark somewhere in each one of us that keeps us going, notwithstanding the obstacles, however big or small. The idea of this campaign is to reignite the spark and inspire people to move ahead in life," Nitesh Tiwari, who directed the campaign for the upcoming season, said."Kaun Banega Crorepati" started 20 years ago, and the forthcoming season 12 will air on Sony Entertainment Television.
