ZIFF-DAVIS
Controlled magazines are not available on newsstands or by subscription but
are distributed to managers and companies which meet certain criteria. This
assures advertisers of reaching the likeliest and largest buyers.
Ziff-Davis sought to remind media buyers that computer buyers rely on ZD publications more than any other when making purchasing decisions.
Ziff's credible test and review of products
was a key factor in the success of their publications.
