Internet Society publishes "The IANA Timeline" document

Alexander Bochmann Tuesday 21 of February, 2017
The IANA Timeline is available here (cache) in HTML format (and as optional PDF download).

It has some of the early history, but it's focus is on the IANA stewardship transition, over to a new non-profit, operating under contracts with ICANN:

“Public Technical Identifiers” (PTI) is incorporated in California as a non-profit public benefit corporation. (The company was originally referred to as PTI, Post-Transition IANA, in the transition documents, thus giving birth to the awkward final name.) This company will be responsible for performing all of the IANA functions regarding DNS names, IP Addresses, and Protocol Parameters under three separate contracts with ICANN
