The last many years have been a time when consumer magazines grew tremendously (and most recently there has been a contraction period in some categories). Previous to that there was a period of several years when the magazine industry was in decline, and the general consensus was that it would, like newspapers are doing now, gradually become a smaller industry. But the magazine industry, due to several factors, rebounded with amazing vigor.
But at the same time, while consumer oriented magazines grew strongly, consumer oriented dance magazines declined. There never have been very many, but now there are even fewer.
