Microsoft has achieved a major milestone after its ad network – spread across Bing,, AOL,, Yahoo, and other properties – reached one billion people last year. 

The news comes via MediaPost (opens in new tab), which cites Microsoft internal data and ComScore as evidence of the huge reach of the company's ad business. 

According to Microsoft, many of the viewers are "overlapping audiences" – the term used for when an audience member uses multiple properties or services from the company at once. As such, 64% of US Windows users also visited a Microsoft service in Q3 2021.

The success of has also played a role. According to (opens in new tab), records an average of 40 million daily visits, ranking 59th in the world. The news service, which often aggregates others, outranks (opens in new tab) by this metric.
