Yahoo Sells To Verizon In Saddest $5 Billion Deal In Tech History. Yahoo was once the king of the Internet, a $125 billion behemoth as big in its time as Facebook or Google are today. The sale will unite Yahoo with another fallen star, AOL, the first web portal Verizon bought last year for $4.4 billion. The CEO Marissa Mayer Treated Yahoo Like A Think Tank, Not A Sinking Ship. And Marissa Mayer officially became Yahoo's last CEO. She is expected to receive a compensation package of more than $23 million as she exits the company, according to a regulatory filing.
