The total number of book titles published annually in North America has approximately quadrupled since television first became available. ██████ █████ ██ ███ ███████ ██ ████████ ██ ███████ █████████ ███████ ██ ███ █████ ████ ██ ███████████ ██████ ███ ████ ██ ████████ ███ ██████ ██ ██████ ██████ ███████ ███████████ ███ ████ ████ ██ █████████ ██ ██████ ██████
The stimulus says that four times as many new books are published in North America each year, compared to when television first became available. Also, shortly after television’s debut, new books sold at much faster rates than before. Now, more books are still selling each year, but the rate of increase is slowing down. However, recently, library use has been flat or falling.
The stimulus lets us infer these conclusions:
The arrival of television in North America did not lead to a decline in new book publications or in book sales.
An increase in new books sold each year does not always coincide with an increase in library circulation.
