i s'pose it's like the music industry itself, the internet changes everything.
more people( like us) go online and dont buy as many (if any) magazines( i used to but Q every month without fail).
So sales plummet, and they have to generate cash somehow, and you get more adverts, also they have to pay wages e.t.c., so then the cover price has to rise. but if i was an advertiser i would be reluctant to splash out much cash towards magazines if no one is reading them.
