Racing horses are big business, and the industry has seen a recent surge in popularity. These days, the racing industry is dominated by thoroughbreds, and most of these horses are registered with the American Quarter Horse Association (AQHA).
Racehorses are bred for speed, and many of them are named after cities, states, or countries. However, they aren't always given human-sounding names. For example, the Most Famous Race Horses Names List, Seabiscuit, was named after the state of Texas. Other names are based on historical figures, places, or animals.
