On This Day In HistoryToday in 1983, 40 years ago: The ARPANET officially changes to using TCP/IP, the Internet Protocol, effectively creating the Internet.

@onthisday what protocol was used before this change?
Marty Fouts@NotMark80 @onthisday NCP the network control protocol was the main predecessor but a range of protocols were experimented with.
Mark Simos@MartyFouts @NotMark80 @onthisday
Do you know the origin and purpose of the OSI model? Was this related to NCP? Or to something else?
davidnewman@markasimos @MartyFouts @NotMark80 @onthisday OSI was an unrelated competitor, literally designed by committee -- the International Organization for Standardization (ISO), and was far more complex. TCP/IP won because it was more lightweight, so easier to implement. #noxp

Thanks for the context and link! I had heard something like that before but never knew the full story.
