"publicity, hype," 1908, from circus slang, "a short sample of a sideshow" (1901), of unknown origin. There is a village of Ballyhooly in County Cork, Ireland. In nautical lingo, ballahou or ballahoo (1867, perhaps 1836) meant "an ungainly vessel," from Spanish balahu "schooner."
Much publicized; hyped-up: two ballyhooed mergers between telephone companies and cable-TV outifts (1920s+)
