Early in 2009, two Google software engineers proposed an experimental protocol on top of HTTP, to try to lower load latency on web pages. That protocol was called SPDY. Once the first studies were done, a new branch was created by another group of engineers. HTTP2 was born, taking as a starting point the lessons learned from SPDY.
