Write an article that answers the following question: How many networks stopped broadcasting games in 2006?
This broadcast was the last for NBC as the American Football Conference network after 33 years (CBS has held the AFC broadcast rights ever since), their last NFL broadcast overall until 2006 NFL season, when they signed on to televise NBC Sunday Night Football, and their last Super Bowl broadcast until 2009 (Super Bowl XLIII). This was also the last time Channel 4 in the United Kingdom would show the Super Bowl - and their last NFL coverage until 2010 - after they had been showing the event since 1983 (Super Bowl XVII). Only Sky Sports would show it live until Channel 5 (UK) joined them in 2003 (Super Bowl XXXVII).  It also marked the last Super Bowl until 2007 for CTV Television Network in Canada after airing the NFL and the event since Super Bowl XVI; from 1999 to 2006 the Super Bowl aired on the Global Television Network.  CTV had aired NFL football since 1970 and the Super Bowl since 1982 (Super Bowl XVI).  It was also the final NFL game for GMA Network in the Philippines until the 2006 NFL Season; GMA had aired NFL football since 1986 NFL season and the Super Bowl since Super Bowl XXI in 1987.  The Super Bowl would be broadcast on TV5 (Philippines), also from 1999 until 2006.  It was also the final Super Bowl in which the Televisa family of networks aired on its own in Mexico, also until 2007, being broadcast on Canal 5 (Televisa Network); Televisa had aired NFL football since 1970 and the Super Bowl since 1988 (at the time, Super Bowl XXII). Azteca 13 likewise would exclusively air the Super Bowl from 1999 until 2006, including Super Bowl XXXVII which would be the next Super Bowl to be played at Qualcomm Stadium.
