More frequent use of press releases distributed by PR Newswire in online conversations builds on a recent research study that measured editorial pickup of content distributed by commercial newswire services.

"Credibility is something that is earned. Clearly, citizen journalists are confident using PR Newswire content in the same vein as professionals in mainstream media," said Dave Armon, president of PR Newswire. "In a tightening economy, ROI is being scrutinized, so maximizing visibility is critically important."

On November 3 Quarkbase, a not-for-profit mashup site consisting of more than 30 data sources and many algorithms, reported that more than 6,414 PR Newswire press releases were referenced in Wikipedia entries, compared to 1,790 for Business Wire, 687 for Marketwire and just five for Globe Newswire.

Since its creation in 2001, Wikipedia has grown rapidly into one of the largest reference Web sites, attracting at least 684 million visitors yearly. There are more than 75,000 active contributors working on more than 10 million articles in more than 250 languages.

Quarkbase also reported 40,400 blog postings of PR Newswire press releases, citing Technorati data, compared to 35,721 blog mentions of Business Wire press releases, 8,952 for Marketwire and 120 from GlobeNewswire (formerly PrimeNewswire).

In a study of traditional media pickup rates, conducted by the independent market research firm Diagnostics Plus during the second quarter of 2008 and announced Sept. 23, 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 GlobeNewswire.

Of those releases attracting attention by the media, the volume of coverage was highest with PR Newswire, followed by Business Wire, PrimeNewswire (now known as GlobeNewswire) and Marketwire. PR Newswire has nearly twice the pick-up frequency as PrimeNewswire and more than twice that of Marketwire.
