What does Nielsen mean by watching “Live” TV?
In the Nielsen TV diary, watching “Live” TV refers to watching programs at the time they are originally telecast as opposed to using some electronic device or service to watch it at a later time (i.e. playback). Some examples of playback devices or services would be the use of Digital Video Recorders, Video-On-Demand, or Video Cassette Recorders to watch programs at your convenience.
