Bing is a search engine that was created by Microsoft. It seemed that most computer companies had some kind of search engine that they were using and they operated it. Microsoft’s seem to be the last computer company to have done this. They created Bing and it was created in the middle of 2009. It provides some suggestions if you’re looking up something.
So if you type in a few words it will come up with a whole phrase that includes those words and they are the most common suggestions. I think that Microsoft is spending so much money on Bing because it is the search engine that they’re proud of and they want to see that it works because they’re always in competition with other computer companies.
