Magazines are dying because of the internet.
The foolish fix at many has been to mimic web formatting and style, which of course is playing to the enemy's strength, and ceding your own which is depth and insight. Look at the food magazines...a pot luck of photos, fonts and sidebars and minimal written content.
Consider The New Yorker, which hasn't changed much over the ~40 years I've been reading it...other than the death/inactivity of several great contributors ( eg Updyke, McPhee, Buford) it hasn't changed much other than adding a crossword puzzle. It appears to be succeeding.
Hmmm.
