Taking a cue from Nielsen's Streaming Top 10, which releases viewership total based on minutes, CBS said it is No. 1 among all networks with 166 billion viewing minutes (excluding commercials). NBC is No. 2 with 130 billion minutes, followed by Fox's 108 billion and ABC's 98 billion. CBS also added this tidbit: “Since it premiered on CBS in 2003, viewers have watched over 3.8 trillion minutes of NCIS and all its spinoffs across broadcast, cable, streaming and syndication.”
