Earlier, the show was supposed to be hosted by Aamir Khan, but now it goes back to the first host of the show, Mr. Bachchan.

Many stars on the host list
Besides Aamir Khan, there were many stars on the possible hosts list, like Anil Kapoor, Shah Rukh Khan, Aamir Khan, and Amitabh Bachchan. But the host crown of KBC, a reality show based on UK game show 'Who Wants to Be a Millionaire?', went to Big B.

Big B was the first host of the show in 2000, and it was his first appearance on Indian Television.

After a four-year break, the show was restarted in 2005 as 'Kaun Banega Crorepati Dwitiya'. But due to Big B's illness, the show ended in 2006.

In 2007, SRK became the host of the show, but the show under Khan could not become as popular as it was under Big B.

According to a source familiar with the matter, “Both, Bachchan and Shah Rukh, respectively brought their distinct individuality on the table, but frankly speaking, Shah Rukh’s histrionics did not do go down well with the audience. There was a vast difference in the TRPs between the two seasons hosted by Bachchan and the third season hosted by Shah Rukh.”

Switch of channels
According to a source, the switch over took place as Star Plus did not renew its contract and so it was given to its rival Sony.

The producer of the quiz game show, Kaun Banega Crorepati, Siddarth Basu said, “Star relinquished the KBC license some time back. And yes, the show is with Sony now.

“All the questions regarding the show and the host will have to be addressed to them. Of course, my company, Big Synergy, looks forward to producing it for them.”
