The New York Times just ran a great article about the enormous cell phone market for regional Mexican music.
Because fans of regional Mexican music tend to be working-class immigrants and their United States-born children, they don’t fit the typical musical consumption patterns of the digital age. They most likely don’t own a home computer, don’t use a credit card and don’t have broadband at home, all prerequisites for an iTunes account. Instead they buy prepaid phone cards with cash and use their cellphones as mobile, personal jukeboxes, often downloading ring tones from their cellular providers for about $3 each, three times the price from iTunes or Zune.
Yet another example of an unexpected use of mobile technology!
