What did she copy from the store in Heathrow?

Amy Nye Wolf had completed a backpacking tour across Europe in the mid-1980s when she saw a store selling music at London’s Heathrow Airport. Wolf recalled that she was tired of the music she had and was very happy to see it. She purchased some music, and returned to the States excited to have found the store. At that time retail outlets in American airports consisted of food service restaurants and newsstands.
It wasn’t until 1994, after Wolf had completed college and worked as an investment banker for Merrill Lynch, that she decided to go into business for herself. She never forgot the music store at Heathrow, and Wolf founded AltiTunes Partners LP, a chain of music stores with 28 locations. All but one are in airports (one is called Train Tunes, and it is located inside Grand Central Station in New York). AltiTUNES’ five year mission is to become the leading brand for small format, extraordinary-location, music and electronics retailing with an expanding network of domestic and international locations.
