some CW prime time shows get on WNLO-TV, Channel 4's sister station." Because of this strong coattail effect, the network that airs the Super Bowl typically takes advantage of the large audience to air an episode of a hit series or to premiere the pilot of a promising new one in the lead-out slot, which immediately follows the Super Bowl and post-game coverage. Entertainment Early Super Bowls featured a halftime show consisting of marching bands from local colleges or high schools; but as the popularity of the game increased, a trend where popular singers and musicians performed during its pre-game ceremonies and the halftime show, or simply sang the national anthem of the United States, "America the Beautiful" or "Lift Every Voice And Sing" emerged.

In an effort to prevent a repeat of the incident, the NFL held a moratorium on Super Bowl halftime shows featuring pop
