Although McLuhan’s observation was made when broadcast television (then an analog medium) was reaching its zenith, the notion of the school as a space set apart from the world just for learning is still with us today. Yet in the present, McLuhan’s “reversal” is itself reversed. The online information level in the class­ room now far exceeds any “level” McLuhan could ever have imagined, just as it easily surpasses what can be found in any printed textbook. Inside is outside; potentially there is nothing outside the classroom. If the television was once thought of as a window on the world of physical time and space, today the computer has become a window on a virtual world seemingly unconstrained by either. All re­ versals aside, McLuhan’s larger point about “information levels” reflecting elec­ tronic media’s potential for extension is well taken.
