A very detailed and technical history from the Internet Society. A good page of links is from Denmark's Vissing Kommunikation . Another entertaining timeline is from BBM, with lots of non-internet historical references. It includes rare treats like the weird RCA 1802 and the little-known Intel 432 . A family tree-like timeline is from the Computer Museum.
Good content makes up for poor formatting.
Also see the illustrated Timeline of Computer Graphics . Also check out Andy Mesa's The Apple Museum . This site is comprehensive and extremely well-designed. It includes a complete summary in one long page. An overview that focuses on the background of the 1984 divestiture restructuring.
