Siddhartha Basu

Basu was born in Calcutta, India, into a Bengali Hindu family, and spent his childhood moving between Bombay, Delhi and Madras. He attended various schools in each city, including Besant Montessori and The Cathedral and John Connon School in Bombay, and Frank Anthony Public School in Delhi, before completing his schooling at the Kendriya Vidyalaya, IIT Madras.

He went on to earn a bachelor’s degree in English Literature from St. Stephen’s College, Delhi, followed by an M.A. in English Literature from Hindu College at the University of Delhi.

Through his college days and after, Basu was active on All India Radio as a voice over artist, announcer and feature producer on its Yuva Vani and General Overseas Services programmes. Shortly after completing his master’s degree, Basu also worked as a documentary filmmaker for TV News Features (TVNF) starting in 1977, for about 8 years, directing numerous short features and popular science films such as Life Before Birth, Avalanches, Frozen in Silver, Moving Images, and Reading Rhesus Macaques.

He briefly worked as a 'cultural attache' for the Taj Group of Hotels from 1982-84. In 1985, he first hosted the inaugural "Quiz Time" programme on Doordarshan. It was a national inter-college quiz show, and featured notable contestants such as Rajdeep Sardesai, Raghuram Rajan, and Jayant Sinha. It quickly became a Sunday evening favourite on Doordarshan’s national network, then the only nationwide channel in the country (which was terrestrial) and was credited with popularizing quizzing across the country.

Along with his wife, former India Today journalist Anita Kaul Basu, he formed the media company Synergy Communications Pvt. Ltd. in Delhi in 1988, which in due course became Synergy Adlabs, then BIG Synergy - after its tie-up with Reliance Mediaworks. Promoted by Siddhartha, Anita Kaul Basu, and Karun Prabhakaran, BIG Synergy built its reputation as a leader in the field of factual entertainment, starting off as one of the country's first independent television production houses.

Following three seasons of Quiz Time (1985, 1986 and 1988), Basu both hosted, produced, and directed a number of shows, namely The India Quiz - The New Age (1989) on Doordarshan, India Quiz Series on Freedom at 50 (1990) on Doordarshan, Alpha Plus (1987) on Doordarshan, Spectrum - A 7-Nation SAARC Quiz (1987), Kissa Kursi Ka (1995), Akshar Mela (1995) on Doordarshan, The Beanstalk Quiz Summit (1997) on Doordarshan, Aao Guess Kare (1997) and, Jaane Kya Toone Kahi (1997) on Home TV, A Question of Answers (1998) on Star World, 3... 2... 1... (1999), Eureka (1999) on Star Plus, Mastermind India (1998-2002) on BBC World, Bluffmaster (2003) on Star One, Kamzor Kadii Kaun (2003) on Star TV, University Challenge India (2003-05) on BBC World, India's Child Genius (2004) on Star World, Howzzat (2004) on Tara Bangla, Heartbeat – Dil Thhaam Ke Khelo (2005) on Star One, Bollywood Ka Boss (2008) on Sahara Filmy, Dus Ka Dum (2008) on Sony Entertainment Television, Aap Ki Kachehri (2008–11) on Star Plus, Kya Aap Paanchvi Pass Se Tez Hain? (2008) on Star Plus, Sach Ka Saamna (2009–12) on Star Plus, Khelo Jeeto Jiyo (2009) on Star TV, Big Money (2010) on Imagine TV, Sports Ka Superstar (2010) on Doordarshan, Jawab Kinte Chai (2012) on Sananda TV, Tech Grandmasters (2012–13) on NDTV, Spell Bee India (2014–15) on Discovery Channel India, India Poochega Sabse Shaana Kaun? (2015) on &TV, News Wiz (2016-19) on India Today, The Big Picture (2021) on Colors TV, and Quizzer of the Year (2024) on SonyLIV, apart from the eight Indian regional adaptations of Kaun Banega Crorepati through the years.

Basu's biggest television success came in the form of Kaun Banega Crorepati (KBC), first produced for STAR Plus in 2000. KBC, as the show is also known, is the licensed Indian version of the globally successful format Who Wants to Be a Millionaire? with Bollywood star Amitabh Bachchan as its host. The second edition of the show began airing in August 2005 and notched up the highest-ever opening in the history of Indian television, going on to sustain its position among the most-watched programmes in the country. The third series of Kaun Banega Crorepati was hosted by Shah Rukh Khan in 2007. BIG Synergy produced the show till 2014, whereas Basu continued as a creative consultant on the show till 2021.

The first two seasons of Sony's hit show Jhalak Dikhhla Jaa, the Indian version of BBC's celebrity dance show, Strictly Come Dancing or Dancing with the Stars, was produced by BIG Synergy, as were the first two seasons of India's Got Talent, on Colors TV. Big Synergy has also produced other landmark shows such as Aap Ki Kachehri - Kiran Ke Saath (hosted by Kiran Bedi), Sacch Ka Saamna and Dus Ka Dum, with Salman Khan as host, on Sony Entertainment Television.

For two decades, Basu worked mainly behind the camera as Big Synergy’s CMD & creative head, but in 2024 he returned to hosting as the quizmaster of Quizzer of The Year (QOTY) on Sony LIV, India’s first all-digital national quiz contest aimed at students in grades IX–XII. As Basu explained in an interview, the contest allowed anyone to play daily via a mobile app, adding points to a leaderboard, and eventually leading to a virtual faceoff. The contest aimed to “buttress a factual culture” among youth. He remarked that, after not hosting since 2005, the producers invited him to return for the finals, which brought him back in front of the camera.

Beyond television, Basu and Anita have also launched Tree of Knowledge Pvt. Ltd. (TOK), an edutainment venture focused on quizzes, e-learning and publishing. Basu, through TOK has produced News Wiz, The Indiannica Quiz League on YouTube, Quizzer of the Year, and The Quizzitok Podcast on YouTube.

Siddhartha Basu is married to Anita Kaul (now Anita Kaul Basu). Anita was a journalist with India Today (1983–88) before co-founding Synergy with Basu in 1988. The couple has two children: a son, Aditya, who works in the Hindi film industry; and a daughter, Medha, who has been working with international organizations in public policy and programmes. Basu often credits Anita for handling the business and logistics at Synergy, enabling him to focus on creative work.

After decades leading BIG Synergy, Basu gradually stepped back from day-to-day management. In 2016, he officially relinquished his positions as Director, becoming a consultant and mentor, before signing off completely in 2018. Today, he is based in Delhi and remains active through Tree of Knowledge, DigiTOK and his quiz ventures. He is widely respected for his integrity and dedication: colleagues describe him as a “strict umpire” who insists on high standards, and media profiles emphasize his role in transforming quizzing from a niche pursuit into mainstream entertainment.
