Sleeper hit is a term used in the entertainment industry for a film that plays successfully for a long period and becomes a big success, despite having relatively little promotion or lacking a successful opening. It is also used in a similar sense for music releases and video games.
Some sleeper hits in the film industry are strategically marketed for audiences subtly, such as with sneak previews a couple of weeks prior to release, without making them feel obliged to see a heavily promoted film. This alternative form of marketing strategy has been used in sleeper hits such as Sleepless in Seattle (1993), Forrest Gump (1994), My Best Friend's Wedding (1997), There's Something About Mary (1998), The Sixth Sense (1999). and Pelli Choopulu (2016).
Screenings for these films are held in an area conducive to the film's demographic. In the case of Sleepless in Seattle, a romantic comedy, screenings were held at suburban shopping malls where romantic couples in their mid 20s to early 30s spent Saturday afternoons before seeing a new film. In theory, a successful screening leads to word-of-mouth marketing, as it compels viewers to discuss an interesting, low-key film with co-workers when they return to work after their weekend.
Easy Rider (1969), which was created on a budget of less than $400,000, became a sleeper hit by earning $50 million and garnering attention from younger audiences with its combination of drugs, violence, motorcycles, counter-culture stance, and rock music.
The 1979 Australian film Mad Max, which sprung from the Ozploitation movement and helped to popularise the post-apocalyptic dystopia genre, held the record for the biggest profit-to-cost ratio for several years until it was broken by The Blair Witch Project in 1999.
The independent film Halloween, which played over the course of fall 1978 through fall 1979 and relied almost completely on word-of-mouth as marketing, was also a sleeper hit, having a box-office take of over $55 million on a budget of only $325,000. Its success caused other slasher films to try the same approach, although few fared as well since horror films heavily rely on opening weekend box-office and quickly fall from theaters. Other notable examples of horror sleeper-hits to follow in Halloween's wake include A Nightmare on Elm Street in 1984, Scream in 1996, The Blair Witch Project in 1999, Saw in 2004, and Paranormal Activity in 2007.
The Romantics' 1980 single "What I Like About You" was a sleeper hit. It was a minor hit upon its release and charted at number 49 on the Billboard Hot 100 in the United States, while not charting at all in the United Kingdom. It eventually became one of the most popular songs of the 1980s.
The R&B singer Raphael Saadiq's classic soul-inspired album The Way I See It was a sleeper hit. Overlooked upon its release in 2008, it ended up charting for 41 weeks on the US Billboard 200. "Poker Face" and "Just Dance" by the pop singer Lady Gaga were both released in 2008 but did not become popular hits until the following year.
The R&B singer Miguel's 2010 debut album All I Want Is You performed poorly at first, debuting at number 109 on the Billboard 200 with sales of 11,000 copies, while underpromoted by his record label. With its singles achieving radio airplay and Miguel touring in the record's promotion, All I Want Is You became a sleeper hit and reached 404,000 copies sold by 2012.
