Final answer:
The statement that is not true is: Total magazine audience size increased by almost 25% from 2014 to 2019, due entirely to the growth of digital magazines, especially mobile web editions and video content.
Step-by-step explanation:
The statement that is not true is: Total magazine audience size increased by almost 25% from 2014 to 2019, due entirely to the growth of digital magazines, especially mobile web editions and video content. This statement is not true because the Pew Research Center's Project for Excellence in Journalism reported that audiences for all the major news magazines declined in 2012.
While digital ad revenue increased, it was not enough to compensate for print revenue loss in newspapers. Therefore, the total magazine audience size did not increase by almost 25% during that period.
