The iTunes Lottery

WSJ online has a great article about the iTunes store and how Apple decides who gets to be on the front page.

Apple has jettisoned some of the conventions of traditional music retailing -- notably, the practice of selling prime promotional spots to recording companies willing to pay for better visibility for their acts. But behind the scenes there's plenty of horse-trading going on that influences which songs are seen and purchased by iTunes customers.

Apple -- now one of the largest sellers of music in the U.S. -- offers home-page placement in exchange for things such as exclusive access to new songs, special discount pricing or additional material such as interviews with stars. Most other big retailers, digital and physical, also seek exclusive offerings, but Apple is especially aggressive and has outsize clout when it comes to the slightly out-of-mainstream music it often emphasizes.
