Most of Microsoft's annual revenue of $143 billion is obtained through licensing software such as Windows and Office and providing cloud storage and computing tools through Azure services. The company's advertising-supported business growth is not too obvious, and the annual advertising revenue from LinkedIn is approximately $2 billion. But Microsoft also said this month that LinkedIn advertising sales have also declined this year due to the impact of the epidemic that has prompted advertisers to reduce spending. Microsoft is weighing the acquisition of TikTok and the acquisition of TikTok's US business from ByteDance. Then Microsoft's advertising business will regain a large number of video advertising services. source
