True, but prosecution at the levels we're talking about is as much a political exercise as a legal one. Wikipedia's background is weak, but Northern Securities Co. v. United States in 1903 [1], one of the first major anti-trust prosecutions, was equally novel by the fact that the US government was choosing to prosecute it at all. The Sherman Anti-Trust Act (1890) had been on the books for better than a decade. Under a unified government, applicability is rarely as much of a question as enforcement.
