14/2 wire has a ground, they just don't count it. The second number refers to the number of non-ground wires. So, 14/2 is 14 gauge, 2 wires plus ground. 10/3 is 10 gauge, 3 wires plus ground. And so on.

Back in the day, they did do separate runs of ground wire. When the standard was first deployed in the US it was common to run the ground as an independent wire that was just connected to the box. This was back in the 50's when two prong outlets were still the standard so you didn't need to connect the ground to the receptacle itself. The standard was also phased in. At first, it was just in places with water, like bathrooms, kitchens, and laundry rooms. By the mid-60s it was all rooms.
