How did ATF get it's acronym..Alcohol, Tobacco & Firearms?

The ATF was a department of the FBI before it was separated. There was a black market for tobacco where tobacco was sold without paying the federal taxes on it. At the time tobacco was rather cheap and the tax was a significant percentage higher. Even today, there is some tobacco smuggled into the US and sold at retail prices. There was also a black market for alcohol during the prohibition. There has been a black market for firearms ever since they put serial numbers on the weapons. z
