American company Apple introduced the iTunes music store in 2003, allowing users to purchase and download individual songs for $0.99 each. By providing inexpensive, legal access to music, iTunes helped revive the music industry and curb piracy. Though competitors like Amazon and Listen.com emerged with their own online music platforms, iTunes maintained an advantage through its large catalog, worldwide availability, integration with iPods and other Apple devices, and strategic partnerships with major music labels and studios. Despite the prevalence of illegal downloading, iTunes has sustained its business model through continued music, video, and app sales as well as revenue from advertisements.
