It used to be that prime-time (evening hours) television viewing was a well-defined and critically important time when audiences across the nation overwhelmingly tuned in to one of the Big Three television networks (NBC, CBS, and ABC).

How do you think your viewing experience might be different if you were answering this question thirty years ago?

As a media consumer, do you time-shift (record a program and watch it later, or watch it online)? Why or why not?
