Week one of the new TV season saw broadcast networks place 93 shows in the top 100 for the key 18-49 demo, led by #1 "Grey’s Anatomy" on ABC, based on the number crunch by the Television Bureau of Advertising (TVB) of both broadcast and cable data from Nielsen Media Research. Of course, that means that cable networks put seven shows in the top 100. Only one was in the top 20, "Monday Night Football" on ESPN. The top 100 breakdown for Households was 92 broadcast/8 cable.

TVBR observation: Another way to look at this is that the entire universe of advertising-supported cable channels had more top 100 shows in the 18-49 demo than The CW (six), but less than Univision (13). TBS had the most of any single cable channel (three).
