Big B, who has been associated with the game show since 2000, posted the pictures of the final episode, which was also attended by "Action Jackson" director Prabhudheva.
The maiden edition of KBC with Amitabh as its host went on air in 2000. The show marked Big B's foray into the world of television.
The eighth edition of the Indian version of internationally popular show "Who Wants To Be A Millionaire", also saw celebrities like Priyanka Chopra, Deepika Padukone and Rani Mukerji playing the game.
In this season, the Narula brothers - Achin and Sarthak - became the first to hit the jackpot by winning the maximum prize money of Rs.7 crore in a special edition of the show and Big B was amazed at the "effort" and "determination" of the two brothers.
The 72-year-old was also inspired by a true story of "fiery young lady" Usha Vishwakarma, who came to shoot with Priyanka. He took to his blog to make a special mention of the "determination and strength" of Vishwakarma from Lucknow who fought back abuse and wretched treatment from the opposite sex.
