A "Channel Lineup" refers to the list of television channels available to viewers through a cable or satellite service. This lineup typically includes a variety of channels, such as local broadcast stations, news networks, sports channels, and entertainment options. Each service provider may offer different channel lineups based on subscription packages. Viewers can often customize their channel lineup by selecting specific packages or add-ons that cater to their interests. For example, a sports fan might choose a package that includes channels like ESPN or NFL Network, while a movie lover might opt for channels like HBO or Showtime.
