History

Although the first successful fax was actually patented in 1843, it wasn't until the 1930s that fax systems had evolved into the form we recognize today. In 1966 the first fax standard was adopted: EIA Standard RS-328, Message Facsimile Equipment for Operation on Switched Voice Facilities Using Data Communication Equipment. This standard made more generalized business use of the fax possible. It became known as the Group 1 standard.

In 1978, the Consultative Committee for International Telephone and Telegraph (CCITT) came out with the Group 2 recommendation. The fax had achieved worldwide compatibility, and this led to a more generalized use of fax machines by businesses and the government.

By the time the Group 3 standard arrived in 1980, fax was well on its way to becoming the everyday tool it is today. This digital fax standard opened the door to reliable high-speed transmission over telephone lines.
