Computer Shopper in the UK was a lot like that back in the 80s and 90s: just a massive wedge of a magazine where the vast majority of pages were ads.

The classified/small ads section alone was enormous. And then you’d have companies that sold computer components include huge swathes of their catalogues and price lists in multi-page adverts. Would have been a real boon for system builders, but I didn’t have the cash back then. I was still in the world of 8-bit micros and 16-bit machines.
