I have been a long time subscriber and it's sad. But, the content seemed to be more and more of guys thinning out their collections as opposed to building new kits. Case in point, the latest and last was a race car centered magazine. They featured a Mercury Marauder that has been making the rounds for a while. A Sunoco Corvette. The Sunoco cars have been built and rebuilt for 10 - 20 years now. Neither really broke new ground and each required 2 - 3 other kits to build the finished model. A resin dirt track model. Finally, their One Great Model feature was a 1990's vintage F1 car. For Pete's sake, Salvino, Ebbro, NUNU and others have been producing new race car kits for several years. There should have been articles from these manufactures, and the new kits from these companies would have made a very interesting magazine.
I also tend to think they relied on the same contributors too much and did not try to cultivate new ones. I may be out to lunch on this one as they may have tried but there was no one to pick up the baton. There just seemed to be a certain amount of sameness to the magazines.
It's business. They need advertisers to pay for the pages, and with advertisers dwindling, the page count dwindled too. Then with dwindling page count came reduced magazine circulation. It's a vicious cycle that in today's climate is impossible to break.
