When did HTTP created?

HTTP (Hypertext Transfer Protocol) was created in 1989 by Tim Berners-Lee while he was working at CERN. The first version, HTTP/0.9, was introduced in 1991, primarily for transferring simple HTML documents. Subsequent versions, including HTTP/1.0 in 1996 and HTTP/1.1 in 1999, introduced more features and capabilities, leading to the widespread use of the protocol on the web.
