The Deutsche Fachpresse - the German Trade Press Association has about 560 members who publish about 3.600 magazines. Only 1065 publication, that’s about 30 % of the 3.600 publication were audited in 2004.
The total number of all B2B publication is estimated between 9.000 – 10.000 titles.
Unfortunately we can present a long term development trend only on trade magazines which have been audited. Please keep in mind that the increase in circulation relates to an increasing number of audited publication, the decrease in circulation does not.
Please keep in mind that the German reunification process does change the base in 1990/1991.
