Microsoft's Bing Isn't a Joke Anymore

Bing is on track to generate roughly $5.3 billion in revenue for Microsoft's fiscal year ended June 30.

Bing's 43 percent growth in search advertising revenue in the nine months ended March 31 is not far off YouTube's 50 percent growth rate, UBS estimates.

Perhaps most crucially, in the year-old Windows 10 operating software, Bing search gets a pole position on the computer home screen in the guise of Microsoft's Cortana digital assistant. Microsoft said this spring that more than 35 percent of its search revenue in March came from Windows 10 computers.
