Once upon a time you’d only know what was coming on your TV if you had a subscription to the local newspaper or to the TV Guide. You could flip channel to channel and find something to watch, and maybe see a preview or two for new shows during commercials. Of course, back then there weren’t as many channels either.
With the internet and the abundance of television channels available the TV Guide is no longer needed. You can watch the guide on your TV, or you can look up shows schedules, channel lineups, and more online. The internet has become something that we rely on for everything, including TV.
