Verizon has taken over Yahoo, completing a $4.5 billion deal that will usher in a new management team to attempt to wring more advertising revenue from one of the internet's best-known brands. Tuesday's closure of the sale ends Yahoo's 21-year history as a publicly traded company. It also ends the nearly five-year reign of Yahoo CEO Marissa Mayer, who isn't joining Verizon. She will walk away from Yahoo with a compensation package currently worth about $125 million, including her severance pay and stock awards that will be fully vested with the deal's completion. Yahoo's email and other digital services such as sports, finance and news will be run by Tim Armstrong, who has been running AOL since Verizon bought that company for $4.4 billion two years ago. Armstrong will now be CEO of a new Verizon subsidiary called Oath, which will consist of Yahoo and various AOL services. About 2,000 Yahoo and AOL workers are expected to lose their jobs as Verizon trims expenses and eliminates overlapping positions.

Verizon won't be getting Yahoo's prized stakes in two Asian internet companies, Alibaba Group and Yahoo Japan. Those will belong to a newly formed company called Altaba, which also will inherit Yahoo's $8 billion in cash and any money that might have to be paid in various shareholder lawsuits filed against Yahoo leading up to the sale. Altaba's stock will begin trading next week under the ticker symbol "AABA." Yahoo's stock will trade through Friday.

Verizon is counting on the combination of Yahoo and AOL to build a strong third alternative in a rapidly growing digital advertising market that is currently dominated by Google and Facebook.
