Chris Seibold of Apple Matters has a great series of posts going on at his site — to which one can subscribe — called “This Day in Apple History”. For May 5, he had a post about the iTunes Music Store, which on 5/5/03, less than one week after its launch, announced it had passed the 1 million download mark for songs. I hadn’t known about this, and the information shocked me. If something bespeaks of popularity through sheer numbers, THAT does. I say this because when it launched, the Music Store was only for Apple computers, and its collection was approximately 200,000 songs – a mere fraction of today’s collection.
