This month marks the 20th anniversary of Microsoft Research, perhaps the most consistently interesting division of the hulking software company. Take a few minutes to peruse the timeline of their work, which ranges from consumer-facing work like Cleartype and spam recognition to the obscure, academic, and quixotic. The names behind the ideas are unlikely to be recognized, but they include geniuses, visionaries, knights, and humanitarians. Billions of dollars per year being expended towards furthering the reach and worth of technology constitutes an important but largely thankless endeavor.Sure, products like Office, Exchange, and other enterprise stuff make up the majority of Microsoft’s income, but I don’t think Microsoft was founded to be a office-tools company. The vision of Microsoft was putting a computer in every home and making that computer as versatile and powerful as possible. Microsoft Research is perhaps more in line with that philosophy than its parent company has been in years.
