Compact discs or CDs were developed in 1979 as a direct successor due to the declining popularity of vinyl records. CDs originally had enough space to store 60 minutes of music. Sony quickly developed the technology extending capacity to 74 minutes and adding wider appeal to the new media format. At the turn of the 80s and 90s CDs drove the price of vinyl down. Compact discs now store 80 minutes with a capacity of 700 MB, and are also a popular medium for storing computer data.
