Email Is Older Than the World Wide Web by Two Decades

Email was invented in 1971 by Ray Tomlinson, who sent the first message between two computers connected by ARPANET. The World Wide Web didn't exist until 1991, when Tim Berners-Lee published his proposal. Email predates browsers, search engines, and social media — yet it remains the primary channel for business communication globally, with over 300 billion emails sent per day.
