Removing Standards Bodies from the PC

The original PC cards developed by IBM were the PC-XT bus and the PC-AT bus. The PC-AT interface was later developed as a standard by the IEEE as IEEE-P966. Today the PCI bus and PCI Express bus are controlled by the Peripheral Component Interconnect - Special Interest Group [PCI-SIG].

The AGP interface standard was developed by Intel, the motherboard design and specification is also controlled by Intel.

The old IDE hard drive standard [ATA] was controlled by the T13 working group of the InterNational Committee on Information Technology Standards. Today the serial ATA [SATA] interface is controlled by the Serial ATA International Organization.

The old SCSI hard drive standard was controlled by the T10 working group. These days Serial SCSI [SAS] retains its protocol but uses the same physical layer as SATA.

The Universal Serial Bus [USB] is controlled by another non-profit corporation.

If it's true that Firewire is moving into disfavor, then it would remove one of the last interface standards controlled by ANSI, or the IEEE. Firewire is also known as IEEE-1394. Recall that the other major bus controlled by the IEEE is the IEEE-1284 Parallel "Printer" bus, currently being obsoleted and replaced by the USB port on most new devices.

RS232 serial ports [EIA-232] are also being removed from the newest motherboard designs. More here

So in another year a new computer will not contain a card or interface controled by a national standards institute. Instead all the boards and interfaces will be controlled by 4 or 5 non-profit corporations.
