I worked in a bookstore at the start of the 1980s. Its magazine section had many hundreds of titles (I stocked them). All of them were more or less that way: mostly ads by page area and page count, with the ratio of ads to content rising as you got toward the back of the magazine (but with most magazines maintaining the last couple of pages for distinctive editorial content). Magazines are generally much slimmer nowadays. Magazine racks are generally smaller and less ubiquitous. I presume the ad dollars have mostly moved onto the web, and the great majority of magazines have shrunk—many disappearing entirely.
