FidoNet is a decentralized, non-commercial communication network founded in 1984 to exchange messages and files between computer users via modem and telephone lines. Utilizing a store-and-forward messaging system, FidoNet allowed users to send and receive public and private messages across multiple connected BBS (Bulletin Board Systems). While it has declined in usage since the Internet’s rise, FidoNet remains active today in smaller communities and developing countries.


The phonetic spelling of the keyword “FidoNet” using the International Phonetic Alphabet (IPA) is: /’faɪdoʊnɛt/

Key Takeaways

  1. FidoNet is a global communication network that allows computer users to exchange messages and files before the widespread use of the internet.
  2. It operates using a store-and-forward technology through a series of nodes and hubs to route messages to their destination.
  3. Despite the growth of the internet, FidoNet is still active and in use, primarily for hobbyists and niche communities.


FidoNet is an important technology term because it was one of the earliest grassroots computer networking systems that played a pivotal role in the development of the internet.

Created in 1984 by Tom Jennings, FidoNet facilitated easier communication over bulletin board systems (BBS), connecting computers worldwide through a message system that utilized a series of protocols for exchanging mail and files.

As a precursor to online forums and email, FidoNet was instrumental in fostering online communities, enabling faster sharing of data and fostering collaborative environments.

The emergence of FidoNet laid the groundwork for many modern communication systems and internet services, making it an essential milestone in the history of technology and digital communication.


FidoNet initially fulfilled the need for an effective communication platform between individuals and communities during the pre-Internet era. It served as a worldwide computer network that allowed users to send and receive messages in the form of public discussions and private correspondence. Users could access numerous discussion boards, known as “echoes,” to exchange information or engage in conversations with like-minded individuals on various topics.

This connectivity significantly fostered the growth of relationships and the exchange of ideas, knowledge, and opinions across geographic boundaries. As a store-and-forward messaging system, it permitted bulletin board system (BBS) operators to share data efficiently via inexpensive long-distance telephone calls, thus offering a cost-effective and decentralized communication solution for people around the globe. Throughout its existence, FidoNet played a crucial role in empowering communities and providing accessibility to information, particularly in regions with limited connectivity.

As an independent network not governed by any single organization, it enabled people to communicate freely without censorship. Schools, nonprofits, and small businesses greatly benefited from its services, laying the foundations for digital communication and collaboration. While FidoNet’s use has largely diminished due to the expansion of the Internet, it still remains an essential milestone in the development of digital communication platforms and a testament to innovative solutions that once connected people around the world.

Examples of FidoNet

Online Discussion Boards: One of the most popular uses of FidoNet during its peak in the late 1980s and early 1990s was the facilitation of online discussion boards known as EchoMail conferences. Similar to modern-day internet forums, these conferences allowed users from around the world to discuss various topics such as computers, politics, hobbies, and more while overcoming the limitations of the traditional BBS setups. Messages were exchanged among FidoNet nodes and automatically distributed to all subscribed members.

Email Communication: FidoNet enabled users to communicate with each other using email-like messages called NetMail. These messages facilitated user-to-user communication between different nodes in the network, bypassing the need for expensive long-distance phone calls or postal mail. NetMail was particularly helpful for users who wanted to communicate across different countries, as FidoNet’s distributed nature allowed messages to be forwarded efficiently and at a low cost.

File Sharing: FidoNet offered a platform for users to share files across different BBS systems. Users could upload or download software, games, text files, and other digital materials that were of interest to them. The network’s file sharing capabilities were particularly significant for computer hobbyists and enthusiasts, as it provided a convenient and cost-effective way to access and distribute software, updates, and patches.

FidoNet FAQ

1. What is FidoNet?

FidoNet is a private worldwide electronic communications network founded in 1984. It allows users to exchange messages, files, and emails through a system of connected bulletin board systems (BBS) using point-to-point communication.

2. How does FidoNet work?

FidoNet works by employing a store-and-forward system, where messages and files are passed from one BBS to another until they reach their intended recipient. This system operates primarily during off-peak hours to minimize any impact on network resources and phone charges.

3. Who founded FidoNet?

FidoNet was founded by Tom Jennings, a computer programmer and sysop (system operator) of his own bulletin board system, known as Fido BBS.

4. Is FidoNet still in use today?

Yes, FidoNet continues to be used by a dedicated community of enthusiasts who maintain and operate BBSes and FidoNet nodes. Although its popularity has waned with the advent of the internet, FidoNet remains an important aspect of BBS history and its legacy continues to influence modern online communication networks.

5. How can I access FidoNet?

To access FidoNet, you must have a compatible BBS client or terminal program that supports FidoNet protocols, as well as access to a FidoNet-enabled BBS. You can connect to a BBS either by dialing into it via a modem or through an internet-based connection known as Telnet. Once connected, you can send and receive messages from other FidoNet users around the world.
