Answer the following Q with stream of consciousness. Debuting on November 23, 2006, the telecasts were originally part of NFL Network's Run to the Playoffs package, which consisted of eight total games broadcast on Thursday and Saturday nights (five on Thursdays, and three on Saturdays, originally branded as Saturday Night Football) during the latter portion of the season. Since 2012, the TNF package has begun during the second week of the NFL season; the NFL Kickoff Game and the Thanksgiving primetime game are both broadcast as part of NBC Sports' Sunday Night Football contract and are not included in Thursday Night Football, although the Thanksgiving primetime game was previously part of the package from 2006 until 2011.\n\nBased on this passage, how long has the nfl been doing thursday night football?
