During the early years, the music sold in the store is decked out with digital locks (DRM). The titles are encoded in AAC 128 kb / s with a sampling rate to 44 100 kHz. It was not until 2007 that significant change is launched: the complete abolition of DRM and doubling the quality of securities (256 kb / s), without additional cost. The success of the platform has never denied and the iTunes Store is the premier source of buying music online. In March 2010, 10 000 million th downloading was performed by Louie Sulcer, won the contest organized by Apple and got $ 10 000 gift card. If today the store has about 15 million shares, it has not always been so. At launch, the store does indeed contain only 200,000 pieces. It will take several years and gradually agreements with the majors for the store actually completes and that the securities in the millions. Gradually, the store will also integrate independent labels.
The chronology of the iTunes Store is that of a "success story". However, the digital market is changing and many are now turning to streaming platforms such as Deezer, Spotify or Rdio. No more pay per unit: one subscription lets the user access to the entire catalog without limit, soon this may be a model that Apple probably also works.
