Rise of USB. Developed by a consortium of companies made up of Intel, Compaq, Microsoft, Sony, DEC, IBM, and Northern Telecom, the Universal Serial Bus (USB) was introduced in January 1996. At that time, the USB 1.0 standard was capable of delivering a transfer rate of 12 Mbit/s. In April of 2000, USB 2.0 was introduced with a transfer rate of 480 Mbit/s. More recently, the USB 3.0 standard reaches transfer rates of 4.8 Gbit/s.
Type-A USB 1.0 plugs and receptacles basically do not exist anymore, since they were officially released in 1996 but replaced in 2000 with the release of USB 2.0, which is when the USB standard really began to take over. When most people think of the standard USB plug, it is the Type-A 2.0 version. USB 3.0 was actually released back in 2008, but it has been slow to catch on.
