The article says modems and point-and-click interfaces led to personal email in 1992. I'm pretty sure the first email (even personal) systems existed long before point-and-click interfaces, and probably also before 1992. But I'm no computer science historian, so could someone knowledgeable correct that statement? -- Kimiko 21:02 21 May 2003 (UTC)
E-mail was first invented for Multics in the late 1960s. However it was limited to a single computer until the internet connected them around 1968. Various private networks (UUNET, the Well, GENIE, DECNET) had e-mail from the 1970s, but subscriptions were quite expensive for an individual- $25 to $50 a month, just for e-mail. Internet use was then pretty much limited to government, academia and other government contractors until the net was opened to commercial use around 1989[?]. Individual e-mail accounts were not widely available until local ISPs were in place, funded by people's desire for web access. This was about 1992. User:Ray Van De Walker
I removed the following statement, because it is factually incorrect: "PARS and IPARS (the airline reservation systems) still (2002) use Baudot code, because it requires only 7.5 bits per character. A bit saved is a penny earned." In fact, IPARS uses a 6-bit shifted code, not 5-bit Baudot. -- Ortonmc 03:58, 11 Nov 2003 (UTC)
Can someone please find a (GNU FDL'd) image for this article. Noldoaran 17:56, Dec 5, 2003 (UTC)
The following was removed from the article as "inaccurate" by an anon user, so I'm leaving it here for those who know more than me:
- The first fax machine was introduced in 1912, known as the Telex-Faxomatic, and primarily used for the transmission of lunch orders from busy factory floors to any number of delies and cafeterias.

Removed from the article, as this does not seem immediately relevant to telegraphy, and I'm not sure that the data-efficiency arguments given are relevant in the current WDM bandwidth glut world:
The Internet was designed with nearly grotesque economies. It is commonplace for internet packets to use less than 1% of their bits for overhead. This cheapness combines synergistically with the Internet's ability to live on other media. A typical cycle occurs when the internet encounters another network, like telex, fidonet, ATM, or (as we are seeing with cable-modem based internet phones) the public switched telephone network:
- First, Internet protocols are tunneled through the other network, as a convenience, usually for some specialized or office application.
- Second, users come to expect the reliable global interconnectivity of the Internet, often for e-mail, or nowadays, for web access. Just because it's old and well debugged, the Internet can seduce a user with a young, poorly behaved proprietary network.
- Third, native applications of the competing network are deprecated, often because "nonproprietary" Internet versions of similar services become available.
- Fourth, an alternative cheaper or higher-speed Internet-compatible medium becomes available, and the organization begins to install it.
- Fifth, the proprietary network is rationalized out of existence as a cost-cutting maneuver, often because the Internet protocols have such low percentages of overhead (i.e. wasted) data.
"The Third Reich invented the first wide-coverage telex system, and used it to coordinate their bureaucracy. It was a true triumph of German efficiency."
Isn't putting true triumph of efficiency and IIIrd Reich in the same sentence borderline apologetic of the IIIrd Reich ? Isn't "German efficiency" itself borderline racist, as racist as "French anarchy" ?

why does telex link point to teleprinter if they talk more about it in telegraphy?
