Bachchan took a break from acting in 1984 to try his hand at politics. The 'Shahenshah', whose proximity to the Gandhis at the time was well-known, contested the 8th Lok Sabha elections from his hometown of Allahabad, in support of his friend, former Prime Minister Rajiv Gandhi. While he won the polls by a huge margin, his political career was short-lived.

Three years later, Bachchan resigned, following the Bofors scandal, vowing never to rejoin politics.

His wife and former actress Jaya Bachchan is a Rajya Sabha MP from the Samajwadi Party.

Bachchan began his television stint as the host of quiz show ‘Kaun Banega Crorepati’ (KBC) in 2000, after a period of professional struggle. Little did he know at the time of signing on the dotted line, that the Hindi adaptation of ‘Who Wants to be a Millionaire’ would go on to become one of the most-watched shows on Indian television.

The Big B hosted the show until 2006, when he fell ill, and Shah Rukh Khan replaced him for the third season. However, in 2010 he returned to the show - that he continues to host till date.

The 'Deewar' star also hosted the third season of ‘Bigg Boss’ in 2009.

Long before the era of Netflix and other digital video streaming platforms that saw several B-town stars turn to the small screen, the Big B was expanding his TV presence. In addition to ‘KBC’, he also did the voiceover for a historic soap, ‘Bharat Ka Veer Putra: Maharana Pratap’.

In 2014, he ventured into the fictional space on television, with ‘Yudh’, a show produced by his banner, Saraswati Creations along with Endemol.

Bachchan often turns into a real-life hero for poverty-stricken farmers across the country. The actor, who owns farmland in the Muzzaffarnagar village of Kakori and has been registered as a farmer by the Uttar Pradesh Seed Corporation, has helped prevent many cases of farmer suicide by paying off their loans.

In addition to helping thousands of farmers across the country, he is often a contributor to relief funds at times of natural calamities, and also donates towards families of martyrs.

In 2018, the philanthropist distributed mechanical equipment to manual scavengers. Bachchan Sr., who was valued at $33.5 million in 2015 by Forbes,is also associated with charities that work for cancer, differently-abled children, and girl-child education. He is also a United Nations ambassador for the 'Girl Child’, and works towards TB and Hepatitis awareness.

Bachchan the businessman was among the most-difficult periods of the superstar’s life. His dream venture Amitabh Bachchan Corporation, set up in 1995, not just failed, but also brought down the actor to bankruptcy.

The company seemed to falter in its every move, from producing 'Mrityudata' - featuring Amitabh Bachchan - that bombed at the box-office to organising the Miss World Show, that failed to bring in the money and added to ABCL's already growing financial woes.

In his late-50s, the Big B was embroiled in legal cases and left with losses of nearly Rs 90 crore and almost reaching a point of losing his iconic Juhu home, Pratiksha.

In 1999, ABCL approached the Board of Industrial and Financial Reconstruction (BIFR) to be rated as a sick company. The actor, however kept going, and bounced back with 'Mohabbatein' and 'Kaun Banega Crorepati', ultimately repaying his creditors.

In 2015, the stalwart and his son, Abhishek Bachchan jointly invested $2.5 lakh in Ziddu, a Singapore-based company.The award-winning actor also actively invests in stocks.

Meanwhile, son Abhishek owns the Pro-Kabbadi team, Jaipur Pink Panthers.
