It’s hard to believe, but the supermarket strike in Southern California has affected the sales of national magazines. Apparently Southern CA grocery shoppers buy a significate amount of magazines at the store. Some estimate a 20% sales drop in monthly magazines like Glamour and also trashy tabloids like the National Enquirer. Time Inc. says that the region accounts for 6.5% of their sales. Wholesalers and magazine distributers are suffering the most. Regional magazines are actually not suffering as much because their readers are largely subscribers. (via Romenesko)
