After Nigeria's independence in 1960, the cinema business rapidly expanded, with new cinema houses being established. As a result, Nigerian content in theatres increased in the late 1960s into the 1970s, especially productions from Western Nigeria, owing to former theatre practitioners such as Hubert Ogunde and Moses Olaiya transitioning into the big screen. In 1972, the "Indigenization Decree" was issued by Yakubu Gowon, which demands the transfer of ownership of about a total of 300 film theatres from their foreign owners to Nigerians, which resulted in more Nigerians playing active roles in the cinema and film. The oil boom of 1973 through 1978 also contributed immensely to the spontaneous boost of the cinema culture in Nigeria, as the increased purchasing power in Nigeria made a wide range of citizens to have disposable income to spend on cinema going and on home television sets. After several moderate performing films, "Papa Ajasco" (1984) by Wale Adenuga became the first blockbuster, grossing approximately ₦61,000 (approx. 2015 ₦21,552,673) in three days. A year later, "Mosebolatan" (1985) by Moses Olaiya also went ahead to gross ₦107,000 (approx. 2015 ₦44,180,499) in five days.
