I wonder if people enjoy reading all those ads?
This can’t be very fun for the readers or contributors but there’s two reasons this happens.
1. There’s usually a couple issues every year that lose money because of the lack of advertising and so the big fashion issues need to make up for this lost revenue.
2. The bigger the issue the more expensive it is to print and ship and the need for more advertising. Surfer magazine has an oversized issue every year that loses money despite the fact that it’s plugged with advertising because the expense to print and ship is so high.
