USB was a attempt to be a “universal” connector. Before USB, you have a whole bunch of different cables and connectors, some small some massive. Parallel, Serial, PS/2, 9-PIN, power etc.
As USB became the standard and replaced all the older types, it went through a bunch of revision to increase the amount of data it could handle. Then you had new physical shapes to fit the needs of smaller devices. Mini USB, Micro USB.
USB C is the equivalent of the original USB 1.0. A universal connector to replace all the older ones.
