Glenn Beck's syndicator runs a astroturf-on-demand call-in service for radio programs

"Premiere On Call, a division of the Clear Channel subsidiary that distributes Rush Limbaugh, Sean Hannity and Glenn Beck, is a service that hires actors to call into radio shows and read a script that purports to be a true story presented by the public. They bind their actors to confidentiality agreements, and disavow any involvement in fraud, saying "Premiere, like many other content providers, facilitates casting--while character and script development, and how the talent's contribution is integrated into programs, are handled by the varied stations.""
