Which Technology Companies Are Truly Disruptive?

The editors of the site you’re reading are hard at work compiling our next list of 50 Disruptive Companies in the fields we cover: energy, biomedicine, computing, communications, and the Web. If you’ve got an idea for one we should consider, let us and your fellow readers know in the comments below.

Keep in mind that this isn’t a quantitative evaluation: we’re not interested in comparing companies on metrics such as patent filings, R&D spending, research employees, market capitalization, or the number of masseuses on staff. We are looking for companies that have done something identifiably disruptive in the past year or so. What does a disruption look like? It is something that threatens the leaders of some existing market, cements a company’s dominance of a market, or creates a new market. Does that sound like any tech company you know?
