Chart: Microsoft's performance under Gates vs. Ballmer
Microsoft has been treading water for a decade, but here is a chart that provides a great visual of how the company's value skyrocketed under Bill Gates and then flattened when Steve Ballmer took over.
Honestly, it's surprising that Steve Ballmer hasn't come under more fire during the past decade for Microsoft's lack of innovation, dearth of new hit products, and a stock price that has continued to tread water.
The graphic below (created by Erik Pukinskis) charts the market value of Microsoft during the past two decades, comparing the CEO reigns of Bill Gates and Steve Ballmer. You have to be a little bit careful with this chart. It's not completely to scale. Notice that the areas between 0 and 5 and 5 and 20 are much larger than the ones between 20 and 40 (and even this between 40 and 60). This gives a little bit of an exaggerated sense of how much Microsoft grew under Gates.
Nevertheless, it's pretty amazing how all of the growth happened while Gates was CEO and then things stagnated as soon as Ballmer grabbed the reigns. Of course, it's also important to keep in mind that the Gates-Ballmer hand-off coincided with Microsoft's big antitrust case with the U.S. government. However, even after the dust settled from that, Microsoft has continued to struggle.
