What's the best newswire service for generated media coverage? According to market research firm Diagnostics Plus in an independent study of commercial newswires, press releases distributed by PR Newswire get used by media more often than copy from competing services and generate more clips when they are picked up.

Press releases transmitted by PR Newswire were used 55% of the time, versus Marketwire's 43% pickup rate, Business Wire's rate of 38% and a rate of 37% by PrimeNewswire, according to the study. Of those releases attracting attention by the media, the volume of coverage was highest with PR Newswire, followed by Business Wire, PrimeNewswire and Marketwire. PR Newswire has nearly twice the pick up frequency as PrimeNewswire and more than twice that of Marketwire.
