My understanding is that they laid off their staff writers a couple of years ago and rely on "outsourcing" articles. Their rate per word is probably too low to attract good writers (or indeed any writers), hence the lack of articles. Frankly, if their rates were any good then *I* would be happy to write articles but they haven't asked me to.
Magazines have to strike a balance. The magazine has various costs including the payment for the editor, writers, copy editor(s), proof reader(s), printing and distribution.
These costs are covered by the money paid by advertisers and the money paid by purchasers/subscribers. When the number of subscribers falls, the magazine has to increase its cover price and/or the cost of advertising. Inevitably, this leads to a further reduction in the number of subscribers and advertisers, requiring more price increases. Soon a tipping point is reached and the magazine fails to cover its costs.
From your description of the current issue, I think that point has been reached.
Some magazines have survived by switching to an on-line model. However, they have to switch before the number of subscribers and advertisers falls too far. Otherwise, they have to start from scratch to try to attract both and that's not easy.
The problem with satellite TV is that it has become a commodity in the UK. There's no longer a huge choice. In fact, for most people, they simply contact Sky and let them do everything. Only a few enthusiasts are interested in receiving foreign channels.
Also, there's not a great number of accessories so the number of satellite-specific advertisers has fallen.
The interest has changed from enthusiasts interested in motorised or multi-LNB systems with lots of gadgets to the man-in-the-street who simply wants to watch TV with the minimum of fuss. His only interest is to pipe TV to other rooms - preferably in HD.
In addition, with Freeview now providing a reasonable choice of channels with quality as good as satellite TV, fewer people even need satellite TV.
So the magazine needs to cover Sky, Freesat, FTA and Freeview reception, with the emphasis on how to pipe TV to other rooms in HD. In addition, with "smart TVs" and "catchup" and streamed TV, the magazine needs to write about those features, too. Frankly, the magazine should do a deal with AVforums to get some decent articles on board, quickly!
