While many recognize actors, directors, and producers as the driving forces behind Bollywood's success, there are individuals who operate behind the scenes, wielding considerable influence without ever appearing on screen. These figures, often unsung, contribute significantly to shaping the trajectory of Bollywood, and their impact can be seen in the success of numerous blockbuster films.

Bollywood, also known as Hindi cinema, is the Mumbai-based Hindi-language film industry. The term "Bollywood" was coined in the 1970s. It’s a portmanteau of "Bombay" (now Mumbai) and "Hollywood". The industry produces films in the Hindi language and is part of the larger Indian cinema.

One key element that defined commercial Hindi films was the masala film, which combines genres like action, comedy, romance, drama, melodrama, and musical elements. The first masala film was Yaadon Ki Baarat (1973).

The 1970s marked a turning point, with Amitabh Bachchan's entry. Films reflected frustration with corruption and unemployment. Deewar (1975) and Sholay (1975) changed the landscape.

The 1990s saw the rise of love stories. Shah Rukh Khan, Aamir Khan, Salman Khan, and Madhuri Dixit ruled the screens. Dilwale Dulhania Le Jayenge (1995) and Hum Aapke Hain Koun (1994) showed love in its filmi glory.

The 2000s made Bollywood a global sensation. Films weren't limited to India, and the diaspora made films like Kabhi Khushi Kabhie Gham (2001) and Kal Ho Naa Ho (2003) box office successes.

In the 2010s, Bollywood embraced big-budget films. Dangal (2016), Baahubali (2015, 2017), and Pathaan (2023) showed the industry's embrace of larger-than-life films.

The rise of OTT platforms has led to a new wave of actors and directors challenging traditional Bollywood norms. Streaming services have removed geographical and language barriers.

While it's difficult to pinpoint one individual who fits the description of having "changed Bollywood history with 9 blockbusters" without acting in a single film, it's important to recognize the contributions of those who have significantly impacted the industry from behind the scenes. Some possible influential figures include:

• Screenwriters: The screenwriting duo Salim-Javed revitalized the industry in the 1970s. They began the genre of gritty, violent Bombay underworld crime films with movies such as Zanjeer (1973) and Deewaar (1975).
• Producers: Yash Raj Films and Dharma Productions have produced new modern films.
• Music Directors and Lyricists: They carried emotions, helping the audience connect with the characters. The voices of singers like Mohammed Rafi, Lata Mangeshkar, and Kishore Kumar became favorites.

These are some people that contributed to Bollywood's success, even if they weren't actors.
