Origins

The core open-source software was developed at MIT starting in 1982 as the PC/IP project, a project to make PCs into first-class citizens on TCP/IP networks. This project began as a Telnet implemented by Louis J. Konopelski under the supervision of

and others, and so some of the inventors of PC/IP decided to exploit their own product. After Donald W. Gillies produced a full-function multi-connection TCP and compatible SMTP for his bachelor's thesis, a mail proxy, it became possible to offer an FTP implementation - which requires two concurrent TCPs. This software, known as "ntcp" (new TCP) in the source tree, could support seven connections on a 128KB IBM PC-XT, and could interoperate with ten different operating systems. The multi-connection TCP languished in the source tree for two years before the FTP founders chose to make it the core of FTP Software, setting the company apart from the other competitors in this space, which were not actively improving PC/IP and were not willing to implement the FTP protocol based upon "ntcp".

Fate

Initially PC/TCP's protocol stacks and network interface drivers were linked into individual application executables, as with PC/IP. By 1990, all PC/TCP applications shared a TSR

specification had largely replaced the built-in drivers. The company had a good run, with a valuation of over $1 billion at one point, but suffered greatly from both internal and external pressures. It had grown rapidly and repeatedly moved physically farther away from its roots at MIT. The founders, though technically adept, were inexperienced as managers. They suffered from in-fighting, epitomized in a public divorce between two of the founders. The company went public in 1994, and maintained profitable growth through 1995, as a dominant supplier of TCP stacks for x86-based machines. They spent two to three million dollars per year on advertising. When Microsoft included a TCP stack at no extra cost in

(as has become standard with all operating systems), FTP lost a significant revenue source. Due to management (which by that time was mostly non-founders) failing to adequately prepare for the transition into supplying network-using applications, FTP was not able meet Wall Street's expectations and its stock price declined sharply. In May 1996, FTP Software announced it was providing Microsoft with various technology for
