In 1954, PR Newswire was the first to create a system for electronic distribution of news releases. Prior to its establishment, companies issuing press releases to the New York media had to messenger, dictate, or mail each copy of their news releases to the city’s daily newspapers and news services. With PR Newswire, companies sent a single copy of their release to PR Newswire's newsroom, where it was simultaneously transmitted to the city's major media points.
PR Newswire created Investors Research Wire in 1965, which directly disseminated corporate news releases to brokerage firms and financial analysts. In 1967, the company acquired the local Los Angeles wire service.
In 1971, PR Newswire was sold to Western Union, which had provided the telecommunications lines and teleprinters that supported the service. In 1972, PR Newswire began using electronic terminals for copyediting. In 1978, the company adopted the Associated Press' computerized message handling and transmission system.

In 1982, PR Newswire expanded through acquisitions like the Philadelphia-based Mediawire in 1983.

PR Newswire began archiving news releases on electronic databases, including NEXIS (now LexisNexis).

In 2002, PR Newswire started MultiVu, its own broadcast and multimedia production company, to create and deliver video and audio news releases, multimedia news releases, satellite and radio media tours, public service announcements, electronic multimedia kits, and Web video.
