An early use in the propagandistic portrayal of current events was the " Boston Massacre " of 1770 , which was employed to build support for the American Revolution . A pamphlet with the title '' A short narrative of the horrid massacre in Boston , perpetrated in the evening of the fifth day of March , 1770 , by soldiers of the 29th regiment '' was printed in Boston still in 1770
