Mobile Radio Technology’s parent company yesterday announced a name change from PBI Media to Prism Business Media. The name change follows the October sale of Primedia’s business information unit to Wasserstein & Co.

MRT’s staff and reporting structure remain intact, but the Web domain used for employee’s e-mail addresses has changed to penton.com. As a result, the new e-mail address for Editor Glenn Bischoff is glenn.bischoff@penton.com and the new e-mail address for senior writer Donny Jackson is donald.jackson@penton.com. However, e-mail sent to their former addresses will be forwarded to the new addresses for the near future.
