Usenet

Usenet is a global online discussion system established in the early 1980s, functioning like a vast network of interconnected message boards. People post messages or files in various categories called newsgroups, which others can read and reply to. Unlike modern social media, Usenet operates on a decentralized model, meaning no single company controls it. It’s used for sharing information, discussing topics, and exchanging files across a wide range of interests. Though less popular today, it remains a historical cornerstone of online communities, emphasizing asynchronous communication and file sharing across diverse groups worldwide.
