In the latter half of the 1970s, as technology advanced, the Philips corporation's compact cassette tape began to supersede LPs as the dominant pre-recorded music format. The format allowed for a much larger 30 to 45 minutes per side for a total of 60 to 90 minutes total, doubling the length allowed for music storage. Later in 1982, Philips introduced the compact disc, with a continuous length of 74 minutes (Later developed to have 80 minutes). As a result of this, artists were given far more room for what they could put on an album, many rarely exceeding the runtime given on tapes and CDs, and double albums became uncommon consequently. This new space also allowed many previous double album releases to be reissued on these new formats on a single unit: "Blonde on Blonde", for instance, was able to be released singularly on cassette and CD when it was reissued.
