Yahoo bought Tumblr in 2013 in a $1.1 billion deal. > In 2017, Verizon merged AOL and Yahoo into its business, creating the media division dubbed Oath. But Verizon admitted late last year that the assets weren't as valuable as it had thought. The company announced in December it was writing down a $4.6 billion goodwill impairment in the fourth quarter as a result of the acquisitions.
