The Alliance for Audited Media (AAM) - formerly known as the Audit Bureau of Circulation (ABC) - has just released its report on newspaper circulation as of last March.
Overall, digital circulation continues to rise, as print circulation stagnates or falls. Total daily circulation numbers were down 0.7% over the last year, and Sunday circulation fell 1.4%. In contrast, digital circulation was up 36%, and now accounts for 19.2% of all newspaper circulation.
For most of the rest of the Top 25, average daily circulation was more or less stagnant. A few papers showed big increases in total average circulation, but most of that seemed to come from the inclusion of "branded editions" (defined as "newspaper-owned products such as commuter, community, alternative-language or Sunday-Select type newspapers") in the total average circulation counts.
