Experian is expected to announce today the addition of the Wenner Media magazine lists to CircBase, its publishing cooperative database.
The Wenner Media files added to CircBase include Rolling Stone magazine with 1.1 million subscribers, Men's Journal with 467,500 subscribers and Us Weekly with 676,100.
Adding the Wenner titles brings the database to 152 participating magazines and 63 million subscribers.
In August, Experian launched a rebuilt version of CircBase that included more frequent updates, expanded modeling capabilities and linking to data from its Z-24 cooperative database for catalogers. The Z-24 database contains 103 million households.
