Turning Condé Nast’s digital department into a solid revenue stream is one of the company’s biggest initiatives. minOnline: How much is that iPad app really worth to an advertiser? As both publishers and their clients still struggle to understand the real reach and impact of digital editions in this new world of the magazine app, Condé Nast and Adobe announced a new set of metrics for assessing digital versions of print brands. Folio: Bonnier is expected to announce that an agency it’s working with is going to recognize the mag+ copies it sells as part of its rate base; mag+ is an initiative now under Moving Media, created by Bonnier for publishers to build tablet editions. Along with Hearst, Bonnier is reportedly partnering with MediaVest, a full-service media specialist. Condé is going a different way, collaborating with Adobe to aggressively monitor, gather and analyze audience engagement metrics with digital editions; the publisher plans to share its findings not only with its advertising clients, but with the publishing industry as a whole. WWD / Memo Pad: Condé Nast Thursday became the first magazine publisher to say it will disclose comprehensive digital sales numbers for the first half of the year. The publisher said it would release single-copy digital sales and digital subscription figures to the Audit Bureau of Circulations. The numbers will be released in August.
