At its launch, the package proved highly controversial mainly due to the relative unavailability of NFL Network at the time; the league used the games as leverage to encourage television providers to carry NFL Network on their basic service tiers, rather than in premium, sports-oriented packages that required subscribers to pay a higher fee; although, as with all other national cable telecasts of NFL games, the league's own regulations require the games to be syndicated to over-the-air television stations in the local markets of the teams. These issues were magnified in 2007, when a game that saw the New England Patriots close out a perfect regular season was simulcast nationally on both CBS and NBC, in addition to NFL Network and the local stations that the game was sold to, following concerns from politicians and other critics.
