Bob Felsenthal, VP-publisher of BtoB, is stepping down from his role at year's end. He will continue to consult until April with Crain Communications Inc. on the merger of BtoB into Advertising Age. Felsenthal joined Crain Communications in 1979 as marketing director at Crain's Chicago Business, moved to Crain's New York Business as associate publisher in 1988, and took over BtoB as publisher in 2000. Working with the BtoB team, he launched many new products, including webinars, virtual trade shows, email newsletters, live events, Media Business magazine, BtoB's Best Creative Awards and original research reports. "Bob has been a pioneer in our company for a number of new publishing solutions, helping us build crucial new models for digital revenue," said Rance Crain, president of Crain Communications. "We're sorry to see him go and wish him the best." "It's been an amazing experience to be part of the b-to-b marketing world, and being part of a truly great company like Crain," Felsenthal said. "I thank Editor John Obrecht and the whole BtoB team for producing the most insightful content available on the b-to-b marketing evolution for the past 13 years. Now I look forward to a new stage in my career." Starting in January, Ad Age will begin delivering a weekly BtoB email newsletter. All existing BtoB newsletter subscribers will automatically receive this new product, the first edition of which will be published Jan. 9. Additionally, the Jan. 6 print issue of Ad Age will have a b-to-b focus and include results of the 2014 BtoB Marketers Outlook survey.
