"men's health" has been criticized for reusing cover taglines. zinczenko replied that 80 percent of magazine sales are by subscription, and those covers differ from the newsstand version. "twenty years of "men's health" has certainly produced several lines that have proven themselves effective at newsstand, which makes up about 20 percent of our print run. we plan to keep using the most effective marketing tools to reach the largest market we possibly can." in july 2010, the magazine was criticized for including tiny credit lines on the cover rather than inside as a possible quid-pro-quo for advertisers. zinczenko said the lines saved readers from having to dig for information and that "men's health" had been including the lines for over a year regardless of advertiser status. a spokesperson for the american society of magazine editors said that no rules were broken. the director for print strategy at a media firm said the mention was "too small of a plug to get brands excited."
