BPA Worldwide has unveilved its list of the top 25 BPA-audited business and consumer magazines, ranked by number of digital-only subscribers, for the first half of 2004. Previously, BPA only tracked digital versions of b-to-b magazines.
No real surprises - tech magazines like Ziff's EWeek are some way ahead of the competition, with 65,000 digital subscribers.
Although the audit supposedly covers "consumer" publications, I personally wouldn't put Java Developers Journal into my all time consumer list.
