JOSS on JOHNNIAC from Rand Corportation is not mentioned as an early time-sharing system. When I was working on the design of the APL\360 supervisor with LMB, JOSS was quite influential. Also there was a PDP-1 based time-sharing system at MIT written in 1961 which should be included.Rdmoore6 03:39, 28 August 2006 (UTC)

Please feel free to add something about them. Speaking personally, I'm always interested to see information added by people who actually worked with the early time-share systems. We already have an article on JOSS and it would be good to link it with this article. As for the PDP-1 system, I'm sure a little information on it would be worthwhile, if we don't already have something. -- Derek Ross | Talk 05:03, 28 August 2006 (UTC)

First mention[edit]

In the proceedings of the 1954 MIT Summer Session on "Digital Computers - Advanced Coding Techniques, page 16-2, it says, "John Backus said that by time-sharing, a big computer could be used as several small ones; there would need to be a reading station for each user." This is the earliest reference to the idea of time-sharing a computer that I have seen in print. This proceedings is available here: Paul McJones (talk) 20:27, 24 June 2010 (UTC)

Right enough. This demonstrates that the concept was known to the inner circle of computer pioneers by 1954, although it would have been difficult or impossible to implement on contemporary computers. However I don't think that those proceedings would count as public dissemination. Only a very few people would have seen them. -- Derek Ross | Talk 06:21, 20 July 2013 (UTC)

John McCarthy did not "leave to work on Project MAC," he left MIT for Stanford and became a professor there in 1962, before Project MAC was started. (See Wikipedia). McCarthy's Reminiscences On The Theory of Time-Sharing are no longer online at Stanford but can be found at . Teager and McCarthy presented a paper titled "Time-Shared Program Testing" at the ACM meeting in August 1959.

McCarthy, Teager, Corbato, Minsky and other MIT professors were active in advocating time-sharing in the late 50s/early 60s. Corbato, Daggett and Daley were the implementers of CTSS, which was demonstrated in 1961. Project MAC began with two man parts: the AI Lab and time-sharing research. The time-sharing research part began by using CTSS at the MIT Comp Center, and then Project MAC obtained its own IBM 7094 and there were two installations running CTSS at MIT. Time-sharing research was initially focused on finding out what one could do with time-sharing. There was a Summer Study at MAC in the summer of 1963, where computer scientists from many organizations experimented with CTSS. By 1965, Project MAC had set up plans to build Multics, a new OS, using CTSS as the development tool.

Stanford batch processing video[edit]

Does anyone know where I might find the video referenced in the section under batch processing? ("Programmers at the universities decried the inhumanist behaviors that batch processing imposed, to the point that Stanford students made a short film humorously critiquing it.") Google gives me nothing.

The section implies that the video was an example of the movement that led to the birth of human-computer interaction as a discipline, so it would be nice if we could have a link to it somewhere. Mariojv (talk) 18:39, 5 October 2011 (UTC)


Is the increase in scientific-based programs like SETI@Home or LHC@Home considered "cloud computing" (and thus not deserving of mention) or should this maybe me mentioned as a form of modern time sharing? Alucardtepes (talk) 19:37, 26 September 2014 (UTC)
