1.16 billion landline phones in 2013 per Wikipedia (CIA world factbook reported 1.26b in 2003; either is likely a roughly good peak global number, a solid mix between high globalization development (eg China & India had started to get large enough economically to install plenty of landlines) and pre high-level cellphone dominance in the developing world):
At peak, how many landline phones (residential) were there? Peak: printed newspaper readership worldwide? Peak: tv viewership (like july 20, '69)
How many people have electricity? Water?
How many active smartphones in use today?
How many machines run any MS OS?
How many worldwide automobiles?
At first it seems like Gomer "Gol-ly" but not really.
