Verizon completed the US $4.5 billion takeover process of email and internet giant Yahoo. The takeover ends Yahoo’s 21-year history as a publicly traded company. 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.
