A Bulletin Board System , or BBS , is a computer system running software that allows users to connect and log in to the system using a terminal program. Once logged in, a user can perform functions such as uploading and downloading software and data, reading news and bulletins, and exchanging messages with other users, either through electronic mail or in public message boards. Many BBSes also offer on-line games, in which users can compete with each other, and BBSes with multiple phone lines often provide chat rooms, allowing users to interact with each other.
Originally BBSes were accessed only over a phone line using a modem, but by the early 1990s some BBSes allowed access via a Telnet, packet switched network, or packet radio connection.
The term "Bulletin Board System" itself is a reference to the traditional cork-and-pin bulletin board often found in entrances of supermarkets, schools, libraries or other public areas where people can post messages, advertisements, or community news.
During their heyday from the late 1970s to the mid 1990s, most BBSes were run as a hobby free of charge by the system operator (or "SysOp"), while other BBSes charged their users a subscription fee for access, or were operated by a business as a means of supporting their customers. Bulletin Board Systems were in many ways a precursor to the modern form of the World Wide Web and other aspects of the Internet.
Early BBSes were often a local phenomenon, as one had to dial into a BBS with a phone line and would have to pay additional long distance charges for a BBS out of the local calling area. Thus, many users of a given BBS usually lived in the same area, and activities such as BBS Meets or Get Togethers , where everyone from the board would gather and meet face to face, were common.
As the use of the Internet became more widespread in the mid to late 1990s, traditional BBSes rapidly faded in popularity. Today, Internet forums occupy much of the same social and technological space as BBSes did, and the term BBS is often used to refer to any online forum or message board.
Although BBSing survives only as a niche hobby in most parts of the world, it is still an extremely popular form of communication for Taiwanese youth (see PTT Bulletin Board System). Most BBSes are now accessible over telnet and typically offer free email accounts, FTP services, IRC chat and all of the protocols commonly used on the Internet.
A notable precursor to the public Bulletin Board System was Community Memory, started in August, 1973 in Berkeley, California, using hardwired terminals located in neighborhoods.
The first public dial-up Bulletin Board System was developed by Ward Christensen. According to an early interview, while he was snowed in during the Great Blizzard of 1978 in Chicago, Christensen along with fellow hobbyist Randy Suess, began preliminary work on the Computerized Bulletin Board System, or CBBS. CBBS went online on February 16, 1978 in Chicago, Illinois.
With the original 110 and 300 baud modems of the late 1970s, BBSes were particularly slow, but speed improved with the introduction of 1200 bit/s modems in the early 1980s, and this led to a substantial increase in popularity.
Most of the information was displayed using ordinary ASCII text or ANSI art, though some BBSes experimented with higher resolution visual formats such as the innovative but obscure Remote Imaging Protocol. Such use of graphics taxed available channel capacity, which in turn propelled demand for faster modems.
Towards the early 1990s, the BBS industry became so popular that it spawned three monthly magazines, Boardwatch , BBS Magazine , and in Asia and Australia, Chips 'n Bits Magazine which devoted extensive coverage of the software and technology innovations and people behind them, and listings to US and worldwide BBSes. In addition, in the USA, a major monthly magazine, Computer Shopper , carried a list of BBSes along with a brief abstract of each of their offerings.
According to the FidoNet Nodelist, BBSes reached their peak usage around 1996, which was the same period that the World Wide Web suddenly became mainstream. BBSes rapidly declined in popularity thereafter, and were replaced by systems using the Internet for connectivity. Some of the larger commercial BBSes, such as ExecPC BBS, became actual Internet Service Providers.
The website textfiles.com serves as an archive that documents the history of the BBS. The owner of textfiles.com , Jason Scott, also produced BBS: The Documentary , a DVD film that chronicles the history of the BBS and features interviews with well-known people (mostly from the United States) from the heyday BBS era.
The historical BBS list on textfiles.com contains over 105,000 BBSes that have existed over a span of 20 years in North America alone.
Unlike modern websites and online services that are typically hosted by third-party companies in commercial data centers, BBS computers (especially for smaller boards) were typically operated from the SysOp's home. As such, access could be unreliable, and in many cases only one user could be on the system at a time. Only larger BBSs with multiple phone lines using specialized hardware, multitasking software, or a LAN connecting multiple computers, could host multiple simultaneous users.
The first BBSs used simple homebrew software, quite often written or customized by the SysOps themselves, running on early S-100 microcomputer systems such as the Altair, IMSAI and Cromemco under the CP/M operating system. Soon after, BBS software was being written for all of the major home computer systems of the late 1970s era - the Apple II, Atari, and TRS-80 being some of the most popular.
A few years later in 1981, IBM introduced the first PC-DOS (MS-DOS) based IBM PC, and due to the overwhelming popularity of PCs and their clones, MS-DOS soon became the operating system on which the majority of BBS programs were run. RBBS-PC, ported over from the CP/M world, and Fido BBS, created by Tom Jennings (who later founded FidoNet) were the first notable MS-DOS BBS programs. There were many successful commercial BBS programs developed for MS-DOS, such as PCBoard BBS, RemoteAccess BBS, and Wildcat! BBS. Some popular freeware BBS programs for MS-DOS included Telegard BBS and Renegade BBS, which both had early origins from leaked WWIV BBS source code. There were several dozen other BBS programs developed over the MS-DOS era, and many were released under the shareware concept, while some were released as freeware.
During the mid-1980s, many sysops opted for the less expensive, ubiquitous Commodore 64 (introduced in 1982), which was popular among software pirate groups. Popular commercial BBS programs were Blue Board, Ivory BBS, Color64 and CNet 64. In the early 1990s a small number of BBSes were also running on the Commodore Amiga models 500, 1200, and 2000 (using external hard drives), and the Amiga 3000 and Amiga 4000 (which had built-in hard drives). Popular BBS software for the Amiga were ABBS, Amiexpress, Infinity and Tempest.
MS-DOS continued to be the most popular operating system for BBS use up until the mid-1990s, and in the early years most multi-node BBSes were running under a DOS based multitasker such as DesqView or consisted of multiple computers connected via a LAN. During the 1990s, a handful of BBS developers implemented multitasking communications routines which, although run under MS-DOS, allowed multiple phone lines and multiple users to connect to the same physical BBS computer. These included Galacticomm's MajorBBS (later WorldGroup), eSoft TBBS, and Falken.
By 1995, many of the MS-DOS-based BBSes had begun switching to modern multitasking operating systems, such as OS/2, Windows 95, and Linux. These operating systems also provided built-in TCP/IP networking, which allowed most of the remaining BBSes to evolve and include Internet hosting capabilities. Recent BBS software, such as Synchronet, EleBBS, DOC or Wildcat! BBS provide access using the Telnet protocol rather than dialup, or by using legacy MS-DOS based BBS software with a FOSSIL-to-Telnet redirector such as NetFoss.
BBSes were generally text-based, rather than GUI-based, and early BBSes conversed using the simple ASCII character set. However, some home computer manufacturers extended the ASCII character set to take advantage of the advanced color and graphics capabilities of their systems. BBS software authors included these extended character sets in their software, and terminal program authors included the ability to display them when a compatible system was called. Atari's native character set was known as ATASCII, while most Commodore BBSes supported PETSCII. PETSCII was also supported by the nationwide online service Quantum Link. (Quantum Link and parts of AppleLink went on to become America Online).
The use of these custom character sets was generally incompatible between manufacturers. Unless a caller was using terminal emulation software written for, and running on, the same type of system as the BBS, the session would simply fall back to simple ASCII output. For example, a Com
