Digital Magazine and Newspaper Editions: The Data
We first present the audited data:
Figure 1: Increase in Audited Business to Business Digital Publications
Figure one describes audited digital publishing activity for business-to-business
publications over the two-year period from June 2005 to June 2007.
� The number of publications reporting digital replica editions for audit purposes
grew from 107 to 230. That represents a growth of 215% for the period.
� The number of digital subscriptions grew from 773,194 to 1,713,637,
representing growth of 222%.
� The penetration of digital subscriptions compared with the total subscriptions
also grew, from 13.3% to 15.0%, demonstrating increasing acceptance of digital
editions.
There were limited data on growth of the penetration based on the number of years that
the digital edition has been offered. While not statistically significant, it appears that
the percentage of digital subscribers grows by about two percentage points per year (i.e.
from 10% to 12% to 14%) in the business-to-business segment.
