Time-sharing was first proposed in the mid- to late-1950s and first implemented in the early 1960s. The concept was born out of the realization that a single expensive computer could be efficiently utilized by enabling multiprogramming, and, later, by allowing multiple users simultaneous interactive access.

Bob Bemer used the term time-sharing in his 1957 article "How to consider a computer" in Automatic Control Magazine and it was reported the same year he used the term time-sharing in a presentation. [6] [8] [9] In a paper published in December 1958, W. F. Bauer wrote that "The computers would handle a number of problems concurrently ...
Incompatible Timesharing System (ITS) is a time-sharing operating system developed principally by the MIT Artificial Intelligence Laboratory, with help from Project MAC.The name is the jocular complement of the MIT Compatible Time-Sharing System (CTSS).
Multics ("MULTiplexed Information and Computing Service") is an influential early time-sharing operating system based on the concept of a single-level memory. [4] [5] Nathan Gregory writes that Multics "has influenced all modern operating systems since, from microcomputers to mainframes."
NLTSS was a microkernel message passing system. It was unique in that only one system call was supported by the kernel of the system. That system call, which might be called "communicate" (it didn't have a name because it didn't need to be distinguished from other system calls) accepted a list of "buffer tables" (e.g., see The NLTSS Message System Interface) [1] that contained control ...
The Dartmouth Time-Sharing System (DTSS) is a discontinued operating system first developed at Dartmouth College between 1963 and 1964. [1] It was the first successful large-scale time-sharing system to be implemented, and was also the system for which the BASIC language was developed. DTSS was developed continually over the next decade ...
The TENEX operating system for the PDP-10 mainframe computer used many features of the SDS 940 Time-Sharing System system, but extended the memory management to include demand paging. [6] Some concepts of the operating system also influenced the design of Unix, whose designer Ken Thompson worked on the SDS 940 while at Berkeley.
The history of Florida can be traced to when the first Paleo-Indians began to inhabit the peninsula as early as 14,000 years ago. [1] They left behind artifacts and archeological remains. Florida's written history begins with the arrival of Europeans; the Spanish explorer Juan Ponce de León in 1513 made the first textual records.
