Clean Reader—“the only e-reader that gives you the power to hide swear words”—sells more than a million ebooks from its online book store. Its app allows users to search the text, and “put a non-transparent “highlight”” over anything potentially offensive. The blanked-out word is replaced, when it is tapped, with one judged suitably safe. So in a passage from its online demonstration—““Don’t tempt me, you little bastard,” growled Vyder”—bastard becomes jerk. In a slice of a David Baldacci novel, “Pick up your damn game, Bobby”, becomes “Pick up your darn game, Bobby”.
