I recently gave a lightning talk about the history of web browsers. 20 slides, auto-advancing, 5 minutes total. It starts with the release of the very first web browser by Sir Tim Berners-Lee in 1990 and culminates with the assembly of the “Big 5” browsers in 2008 (Chrome being the last one to the party). The central theme is about how competition (or lack thereof) has shaped the web.
