Yahoo is an American web services provider that was founded in 1994 by Jerry Yang and David Filo. Initially starting as a directory of websites, it quickly evolved into a popular search engine and web portal, offering various services such as email, news, and finance. Over the years, Yahoo has undergone several changes, including acquisitions and restructuring. It was acquired by Verizon Communications in 2017, which integrated it into its media division. Despite facing competition from other tech giants, Yahoo remains a recognizable name in the online world, particularly for its email service.
