Vendor lineage
Sytek - broadband LANs, and NetBIOS
Ran local networks over cable television plant, and left behind an interface that outlived the company by decades.
Sytek built local area networks on broadband coaxial cable - the same medium cable television used - which let a network cover a campus rather than a floor and carry several channels at once. It is better remembered for something smaller: the NetBIOS interface it developed with IBM, which became the foundation of PC networking for a generation.
Broadband LANs lost to baseband Ethernet for the reasons most things in this period lost: cost, simplicity and the pace at which the winning option got cheaper. Running a network over CATV plant required radio-frequency engineering that an ordinary site could not staff.
NetBIOS is the more interesting legacy and a recurring lesson: the durable artefact of a company is often not its product but an interface it defined, which then long outlives the hardware, the company and eventually the sense of what the acronym meant.
