Looking at those viewers who tuned in to the first week of The Jay Leno Show reveals indicators of some program preferences that youbd expect and some that would surprise.B The two charts below examine the programming airing at weeknights at 10PM that the Leno audience viewed prior to the September 14 premiere.

The first chart reveals televisionbs emerging long tail.B The chart shows the percentage of the Leno audience that watched any of 650 different programs airing at 10PM on weeknights across broadcast and major cable networks in the weeks of August 31 and September 7, ranked in descending order by the percentage of the Leno that tuned-in.

Only 10 of the 650 programs attracted 5% or more of the audience that went on to view at least one episode of The Jay Leno Show during the week of September 14.B Of the 10, 9 of the programs were on NBC.

The next 30 programs each attracted 1% of more of the Leno audience.B Half of those next 30 programs aired on ABC, led by 20/20 and Primetime news programs.
