Verizon Communications on Monday announced that it had entered into a definitive agreement to acquire Yahoo’s operating business for approximately $4.83 billion in cash. The deal, which comes on the heels of Verizon’s $4.4 billion AOL purchase last year, will allow it to expand its digital advertising business. The purchase will provide Verizon with Yahoo’s ad tech tools, including BrightRoll and Flurry, as well as Yahoo’s search, email and messenger assets. It brings to a close Yahoo’s attempts to find an interested suitor for the company.
