FireWire was initially popular among users who used it to connect data storage devices and digital cameras, although it was also popular in industrial systems. It was preferred over USB 2.0 due to its greater effective speed and power distribution.
To develop IEEE 1394 required the use of 261 patents that were held by 10 companies. The companies holding these patents formed a patent pool called MPEG LA, to whom they licensed patents.
MPEG LA then sublicenses these patents to companies implementing IEEE 1394 under the patent pool license. A royalty of $0.25 per unit is then payable to the manufacturer upon completion of each product.
