What Happened to Token Ring? IBM’s Network That Lost the Office to Ethernet

#TechHistory #RetroComputing #ComputerHistory What happened to Token Ring, IBM's once-dominant office networking technology that promised reliable, collision-free communication? Discover how Token Ring became a trusted standard in corporate America—and why Ethernet ultimately replaced it, despite IBM's powerful influence and engineering expertise. Introduced by IBM in 1985, Token Ring transformed how businesses connected personal computers, servers, and mainframes. Built around IEEE 802.5, its orderly token-passing system offered predictable network performance and became a major force in enterprise networking. This documentary explores the rise of IBM Token Ring, its rivalry with Ethernet, the role of Madge Networks, and the expensive hardware and cabling that limited its future. From the arrival of 10BASE-T and Fast Ethernet to the development of network switches and Gigabit Ethernet, discover how a cheaper, more adaptable technology conquered the office networking market. We also examine IBM's retreat from networking hardware, the final attempts to revive Token Ring, and the lasting legacy of a technology that helped shape modern computer networks. 👍 If you enjoy documentaries about forgotten computers, classic networking technologies, and the rise and fall of legendary tech innovations, like this video and share your thoughts in the comments! 🔔 Subscribe for more in-depth documentaries exploring the fascinating history of computers, forgotten technologies, and the innovations that changed the digital world. #TokenRing #IBM #Ethernet #NetworkingHistory #VintageComputers
