Walter Karl completes brand-name transition

Since acquiring Penton Media, Walter Karl's business partner Prism Business Media has completed its brand-name transition.

The new-formed synergy, which is now operating under the Penton Media brand, is a business-to-business media and information company that serves more than 6 million business professionals monthly.

Penton Media's market-leading brands focus on 30 industries.

Walter Karl markets 3.2 million Penton Media magazine or newsletter subscribers online and offline.

Effective immediately, all the files formerly managed by Prism will be branded under the Penton Media Inc. name but remain with Walter Karl.
