Book TV is the name given to weekend programming on the American cable network C-SPAN2 airing from 8 a.m. Eastern Time Saturday morning to 8 a.m. Eastern Time Monday morning each week. The 48 hour block of programming is focused on non-fiction books and authors, featuring programs in the format of interviews with authors as well as live coverage of book events from around the country. Book TV debuted on C-SPAN2 on September 12, 1998. While the primary mission of C-SPAN2 is live coverage of the United States Senate, Book TV programs are sometimes also scheduled to air during the week when the Senate is not in session.
