4 internet protocols on the wall
The oldest internet protocol still running
Email, running 55 years since 1971.
55y 31d Email has outlasted every other internet protocol here.
Email (1971), IRC (1988) and RSS (1999) lead the 4 internet protocols still running. The list spans 38 years, from Email to Bitcoin (2009), and only counts products with a written entry and a founding date; nothing here is dated from a Product Hunt launch. Closed internet protocols are on the closed list.
