The number of American Business Media members stands at 326, up from 288 a year ago.
New members added in the past year include online pure plays such as iCopyright and TradeComet.com, as well as Lincoln Healthcare Events. Cygnus Business Media, which left ABM in 2002, has rejoined the organization.
"I need to reposition Cygnus with advertisers, and I'll learn a lot from ABM on how to do that," said Carr Davis, who took the helm of Cygnus (along with co-CEO Anthony O'Brien) earlier this year to ramp up the media company's online efforts.
Advantage Business Media, which was created this year by former Cygnus Publishing president Richard Reiff, has also joined ABM's ranks.
Yahoo! and Outsell Inc., which both joined ABM as associate members, this year were reclassified as media members, which entails full voting privileges.
ABM also welcomed three companies from India: Infomedia India, ITNation India and Scope e-Knowledge Center.
Perhaps in a reflection of the increased membership, this year's Top Management Meeting drew a record 310 people, compared with 280 attendees last year.
