“The phenomenon of appointment TV, where viewers in vast numbers mold their personal schedules to a network’s, is pretty rare these days. It’s mostly a relic of an era before home VCRs gave the audience a measure of scheduling control. An explosion of newly liberating innovations (streaming video and mobisodes; podcasts, vlogs and TiVo) gives you ever more power over what you see and hear — and better access to it, as it spreads everywhere. It’s a gold rush, all right, across the digital universe, with bazillions of dollars riding on which gadgetry and content strike the public’s fancy.”
