MICROSOFT Corp.'s tumultuous fall on the stock market during the past 13 years has largely been fueled by missteps in the consumer products market.
Though Bill Gates had significant control until 2006, soon-departing Chief Executive Steve Ballmer ultimately held responsibility over Microsoft's vast empire.
Here's a look at some initiatives that didn't work out as planned.
Microsoft Tablet PC: Nearly a decade before Apple released the iPad, Microsoft had developed a version of Windows XP suitable for tablets. The tablet was controlled by a stylus.
Bill Gates said Tablet PCs, as Microsoft called them, would be ubiquitous within five years. Gates and Ballmer missed the mark by failing to see the need for hand-touch technology and user-centric marketing'"two key elements behind the iPad's success.
Microsoft released a tablet in 2012. But people found it difficult to use, and Microsoft couldn't convince developers to make apps for the tablets despite Ballmer's appeals to the developer community.
Microsoft took a $900-million loss on $19.9 billion in revenue in the most recent quarter because of weak tablet sales. Recently the company cut prices of a couple of models. It also lost out on big contracts, such as with the Los Angeles Unified School District, which plans to give all of its students Apple iPads instead.
Despite not succeeding on its own, Microsoft hasn't made its widely used Microsoft Office software available on the Apple. That's sent many potential customers to the competition, including Google Drive.
