#TodayILearned that mass-market paperbacks are nearly dead. In fact, they've been dying almost since I began reading, having peaked at 49% of the book market in 1970, and being down to 3% in 2024, with ReaderLink having stopped distributing mass-market paperback books at the end of 2025.
I even looked at some #BookTube videos, and the young hosts referred to trade paperbacks as "traditional" books, and "the usual type" of book, and finding MMPBs odd and old-fashioned. #TIL
