Never in history has technology been so advanced and successful. Can you imagine a world without the PC, smartphones, or Google? But not every tech idea has had such unbelievable success. Many top tech companies produced gadgets that just sunk, despite a great deal of research and fanfare. Here are the ten biggest blunders we’ve seen in the last 40 years.

#1 – Microsoft Zune

The Zune was Microsoft’s answer to Apple’s iPod. Released in 2006 in Black, Brown or White, the Zune was intended to be a social media player, allowing users to share songs between their players. However, the Zune immediately faced comparisons to the iPod, and was the butt of many jokes for it’s brown color. In addition, on December 31, 2008, all Zune players froze and became bricked due the their software not being able to handle the Leap Year. Microsoft did produce additional generations of the Zune, but finally put it out to pasture in October 2011.
