A box office is a place where tickets are sold to the public for admission to an event. Patrons may perform the transaction at a countertop, through an unblocked hole through a wall or window, or at a wicket.

By extension, the term is frequently used, especially in the context of the film industry, as a synonym for the amount of business a particular production, such as a film or theatre show, receives. The term can also mean factors which may influence this amount, as in the phrases "good box office" and "bad box office".

Box office business can be measured in terms of the number of people who see it or the amount of money raised by ticket sales (revenue). The projection and analysis of these earnings is very important for the creative industries and often a source of interest for fans. This is predominant in the Hollywood movie industry.

Some complain that industry focus on profit has diminished the attention given to film as an art form. However, analysis of the financial success of films is very influential for the production and funding of future works.

Khan, who made his acting debut with a minor role in the drama Biwi Ho To Aisi (1988), had his first commercial success with the blockbuster Maine Pyar Kiya (1989), for which he won a Filmfare Award for Best Male Debut.

In 1999, Khan won a Filmfare Award for Best Supporting Actor for his extended appearance in Kuch Kuch Hota Hai (1998), and since then has starred in several critical and commercial successes, including Hum Dil De Chuke Sanam (1999), Tere Naam (2003), Mujhse Shaadi Karogi (2004), No Entry (2005), Partner (2007), Wanted (2009), Dabangg (2010), Ready (2011) and Bodyguard (2011), which has become the second highest-grossing Bollywood film of all-time.
