For better or worse, Apple has been peddling digital wares for 10 years through its iTunes store. What started as a 99-cent, iPod-centric music seller has evolved into the billion-dollar behemoth we know today.
iTunes sells 35 million songs in 119 countries, movies in 109 countries and 850,000 iOS apps in 155 countries. After launching iTunes in 2003, Apple added podcasts in 2005, movies in 2006, and the App Store in 2008, along with iTunes U. It's not the most navigable or inexpensive place to shop for media, but the iTunes store is deeply embedded in the Apple ecosystem.
Tomorrow will be just another day of downloads and syncing, but today you can reminisce about the top albums and songs from every year that iTunes has been around, and continue to be non-plussed by the fact that the iTunes store eventually got to sell Beatles music. [MacRumors, AppAdvice]
