C-SPAN , an acronym for Cable-Satellite Public Affairs Network, is a private, nonprofit American cable television network.
Created in 1979 by the cable television industry as a public service that offers television broadcasting of federal government proceedings and other public affairs programming by its three television channels C-SPAN, C-SPAN2 and C-SPAN3
On weekends C-SPAN2 dedicates its schedule to non-fiction books, book events and authors, with 48 hours of programming called Book TV, first launched in September 1998. This includes: programs featuring historical books and biographies of public figures; In Depth, a live, monthly, three-hour interview with a single author; After Words and repeats of Booknotes.
After Words is an author interview program featuring guest hosts interviewing authors on topics with which both are familiar. The program was developed as a new type of author-interview program after the end of production of Booknotes, which was C-SPAN’s previous author-interview program. Booknotes was broadcast originally from 1989 to 2004, with a one-hour one-on-one interview of a non-fiction author as its format.
Repeats of the interviews remain a regular part of the Book TV schedule with the title Encore Booknotes. The Book TV weekend programming also includes coverage of book events such as panel discussions, book fairs, book signings, readings by authors, and tours of bookstores around the U.S
