BusinessWeek published a list of the World’s Most Influential Companies, giving recognition to the companies that "introduce new ideas that their competitors are then forced to adopt". On the list are many of the usual suspects that might come to mind such as Apple, Google, Microsoft, Craigslist, Facebook, Sirius, Nielsen (all of which have pioneered concepts which have influenced mainstream consumer behavior).
But interestingly, from India – HCL Technologies made the list and not Infosys or Wipro. From the BusinessWeek profile of the company:
The info-tech services provider specializes in everything from managing tech infrastructure to creating custom software solutions. Where it has the potential to be most influential, however, is not technology, but management. Vineet Nayar, CEO of the Noida, India-based firm, has adopted a novel philosophy: Management should be accountable to employees. He puts that into practice by publishing top managers’ performance reviews on the company’s intranet, by installing a one-stop service desk for employees problems on anything from laptops to bonuses, and by posting answers to dozens of questions employees leave for him each week online. Several top technology executives have made the pilgrimage to HCL’s (HCLT) headquarters to see Nayar’s philosophy at work, and Harvard Business School professors are already teaching case studies about it.
Also from India, SKS Microfinance made the list, although it is hard to tell how this can be a "world’s most influential" firm given that their primary market is India alone.
Other notable and somewhat surprising firms on the list were Autodesk and Intuit (makers of Quickbooks), who seem to have been chosen because they dominate their markets, even though there arent many drastically new ideas being introduced by them.
