The practice of using sensational or exaggerated publicity and hype to attract attention and audiences, named after the famous showman P.T. Barnum.
From P.T. Barnum (1810-1891), the legendary American circus promoter and showman, plus the suffix '-ism' meaning a practice or doctrine. Barnum became synonymous with theatrical promotion and audience manipulation in the 19th century.
