According to a recent book, right now in America there are 1,780 commercial television stations, 15,503 broadcast radio stations, 1,331 newspapers, 2,000,000 billboards, and 5,821 movie theaters. Worldwide there are 7 billion cell phone subscriptions (comprising 4.77 billion mobile users, many of whom have more than one phone) and 1,276,011,353 billion websites—and this information became obsolete by the time it took me to say these two sentences because there will be more of the above (except for print newspapers).
