Apple charged $1 per port for FireWire, and the free standard won

FireWire (IEEE 1394) was Apple's high-speed serial bus, developed with Sony and Panasonic and built into Macs and Sony DV camcorders from 1999. At 400 Mbps it was roughly thirty times faster than USB 1.1's 12 Mbps, and it moved data without burdening the CPU — which is why the first iPod (2001) synced over FireWire and why video editors adopted it on sight. It looked like the PC's next universal port.

Then came the pricing. Apple began charging device makers a $1 licensing fee per FireWire port in 1999, while USB carried no fee at all. When the USB 2.0 specification landed in April 2000 at 480 Mbps, Intel — which had initially supported 1394 — pulled back and threw its weight behind USB 2.0. Intel chipsets were the backbone of the PC industry, so once the free bus matched FireWire's speed class, makers of drives, cameras and cards had no reason to pay the toll.

FireWire survived where its technical edge was real — digital video capture, low-latency pro audio, daisy-chained drives — and Apple kept ports until its last FireWire Mac in 2012, by which time Thunderbolt, co-developed with Intel, had taken over the role. In 2025, macOS 26 removed support outright. USB went on to absorb everything FireWire offered — speed, bus power, full-duplex transfer — without the licensing baggage.

Free beats faster when the toll sits on the port

Per-port royalties are a toll on adoption, and makers had a toll-free alternative arriving in the same Intel chipset generation.

480 Mbps erased FireWire's speed argument, so the fee became the only difference buyers' OEMs could see.

The fee signaled Apple treated FireWire as rent rather than infrastructure, and partners priced that risk into their choices.

FireWire's genuine advantages — DMA transfers, peer-to-peer networking, sustained streams — mattered mainly to professionals, too narrow a base to carry the standard.

A standard is adopted like a language: whoever lowers the cost of joining wins. Tax every port and you fund your rival's volume — monetize the ecosystem, not the right to connect.

USB became the universal serial bus its name promised, and the ecosystem revenue Apple wanted came instead to whoever sold the devices. FireWire spent the 2000s as a professional-video-and-audio interface, vanished from Macs after 2012, and was formally deprecated in macOS 26 in 2025. Thunderbolt, Apple's later bus with Intel, adopted the opposite playbook: royalty-free to implement, monetized through certified cable and device ecosystems.
