Stefan Weitz, Microsoft's Director of Search, gave a TED Talk, which TED recently uploaded. The topic of his talk is "how you can win when you're not supposed to".
"You need some kind of argument you can use to justify this existence," he says.
This wasn't a direct reference to Bing's existence, but it does bring back some memories about Microsoft's launch of a new search engine not that long ago (when it already had one at live.com).
Here's what the description says about Weitz:
Stefan Weitz is the Director of Search at Microsoft and is charged with working with people and organizations across the industry to promote and improve Search technologies. While focused on Microsoft's product line, he works across the industry to understand searcher behavior and in his role as an evangelist for Search, gathers and distills feedback to drive product improvements. Prior to Search, Stefan led the strategy to develop the next generation MSN portal platform and developed Microsoft's muni WiFi strategy, leading the charge to blanket free WiFi access across metropolitan cities. A 12-year Microsoft veteran, he has worked in various groups including Windows Server, Security, and IT. Stefan is a huge gadget 'junkie' and can often be found in electronics shops across the world looking for the elusive perfect piece of tech.
If your'e a fan of either Bing or TED Talks in general, give it a watch. While you're at it, why not watch a few interviews we've done with Weitz over the past few years:
