CBS’s new Silicon Valley legal drama Cupertino tops the Promo Mojo ranker for the week ended October 4, making it TV’s most promoted show. The network also grabs fourth place for its new vampire sitcom Eternally Yours. Cupertino, which comes from Robert and Michelle King, premieres Thursday, October 8 at 10 p.m. ET/PT.
CBS is joined by fellow traditional broadcast network NBC, which promotes new family-focused action drama Line of Fire in second place, and Fox, which hypes returning comedy-drama Best Medicine in fifth.
Following two weeks in which traditional broadcasters swept the ranking, this time one cable network cracks the top five: TBS, with MLB Baseball in third place.
Notably, Line of Fire and Best Medicine are tied for having the highest iSpot Attention Index (114) in the ranking, meaning viewers were on average highly likely to watch their promos all the way through (vs. interrupting viewing by changing the channel, pulling up the guide, fast-forwarding or turning off the TV).
