I was the senior writer at PC Magazine from 1993 to 1998 and remember the days when the magazine actually turned away advertising because the printer couldn't physically fit any more pages into the magazine. The dull thud of a 500-plus-page edition of PC Magazine hitting the bottom of a mailbox has been a distant memory as more recent editions have struggled to stay above 100 pages.
While PC Magazine will apparently continue on the Web, it's indeed the end of an era.
