screenseller
n.— «Yes24, an online bookstore, said the original novel on which the film “The Reader” is based, published in 1995 by German author Bernhard Schlink, saw an average of 19 copies sold monthly since the book was first published in Korea in 2004. But in the month after the film’s release, the number of books sold jumped to 4,733. The novel now ranks as the No. 2 best seller on Yes24 and at No. 4 at Kyobo Bookstore. The industry calls these kinds of books “screensellers,” a portmanteau of “screen” and “best seller.”» —“Book sellers rejoicing over film adaptations” JoonAng Daily (South Korea) Apr. 17, 2009.
