5. iPod (2001)
It’s safe to say that no other brand has impacted the digital music market quite like Apple. To this day, the iPod is one of the most popular and easy to use portable music players to ever exist. Since launching the first generation device in October 2001, there have been consistent updates, redesigns and new features released pretty much on a yearly basis. The latest models have extended beyond music at this point, offering radio streaming, retina screen video display for TV shows and movies, and Wi-Fi connection for surfing the Internet.
