Beginning in 2009, the Print Measurement Bureau will release its database of information on magazine readership and reader buying habits twice a year, in March and September.

“The enhancements are being made in response to member requests for more current, up-to-date information on magazine readership and on trends in product and brand usage,” PMB said in a release.

PMB is a non-profit organization, representing the interests of Canadian publishers, advertising agencies, advertisers and other companies. It currently tracks readership for 115  publications and consumer usage for over 2,500 products and brands.
