I recall seeing a film shot from a camera placed in the rafters of a gym, whith two NY Times cut into hard content and advertising and laid on the floor for comparison.
Computer Shopper was intended to be all ads, as is Hemming’s. Not sure it should count.
Looks like the winner is bridal magazines. Which is some how appropriate…
I read somewhere that Computer Shopper only had enough editorial content to qualify for the lower postal rates for periodicals rather than the more expensive rate for commercial mail.
