In 1968, George A. Romero's movie "Night of the Living Dead" combined reanimated corpses (zombies) with cannibalistic monsters (ghouls). With this, it created new movie monsters more terrifying than either of the two alone. The term "ghoul" was the one actually used in the movie. The term zombies came later, after the movie was released. Romero had never thought of them that way; he said he thought of the Caribbean creatures, when he heard the term "zombies".
