What is Bing?

Bing is supposed to be the main Google competitor. The search engine created by Microsoft and powered by Yahoo - it's a challenge!

“Yahoo would be allowed to sell search ads on Bing.com as well as its own site, giving it more search inventory to sell and making it a bigger player in the search sales front. It would also immediately be able to save millions by not having to maintain its own search infrastructure. The latest terms of the deal underscore Microsoft’s devotion to developing and owning technology vs. selling media.”
