Foxnet aired the Fox network's prime time schedule and its children's programming blocks (originally Fox Kids, then FoxBox/4Kids TV from September 2002 onward); beginning with the network's assumption of rights to the NFL's National Football Conference in September 1994, it also carried telecasts of sporting events produced by the Fox Sports division, though being a national service having to choose from certain games rather than taking regional coverage, it was possible for an NHL, NFL or MLB matchup with teams with no rooting interest in a certain area to be of no interest to those viewers. In some areas where Foxnet was offered, affiliates of other networks carried secondary affiliations with Fox to air the network's sports programming (and in some areas children's programming) over-the-air; during this time, some cable systems blacked out Foxnet whenever sports programming was aired due to syndex laws.
