Bing (the search engine formerly known as “Live” formerly known as MSN) has had some success because of their connection to airline reservation systems, enabling them to serve up flight information directly in search results.
Now Google has purchased ITA, an airline reservation system, for some $700 million.
Watch pretty much the last reason to use Bing evaporate rather quickly now.
This is why Google remains the 600 pound gorilla in Search. Any time a competitor does something both new and sensible, Google includes it in themselves as fast as they can. And with their latest software, Caffeine, they can do so FAST.
