People buy magazines for the content, the ads are an unfortunate side effect of the low cost.
The unwanted side effect of that is probably the little greedy voice inside people that causes them to buy even more things they don’t need because all of the dressing up made it sound appealing.
The same went for the gaming magazines (White Dwarf particularly). Even the ads that were just price lists were fascinating, just to see what was available to go and check out on the next trip to a games store.
It was probably about 95% ads and just a few articles. Before comparison price sites it was a good way to find cheap prices for computer parts
Trust me, there's a market for people who want ads.
However, ads when I'm not looking for them can just fuck right off.
