CBS Fall 2026 Premiere Week Draws 8.63 Million Viewers

By Grace Kim

CBS averaged 8.63 million viewers during its fall 2026 premiere week in the week of Oct. 4, according to Nielsen live+7 multiplatform data. The total rose 14% from CBS’s 2025 premiere week, which began Oct. 12.

Live+7 is the seven-day viewing window CBS and Nielsen used for the multiplatform totals, combining linear television and streaming. It differs from live+same-day measurement, which CBS used for the “Cupertino” comparison.

Which programs powered the result?

“Marshals” led the returns with 15.14 million viewers across live+7 multiplatform viewing. CBS placed the drama at No. 1 among entertainment shows for the week in both linear and streaming.

“Tracker” followed with 13.86 million viewers. CBS also named “Marshals” and “Tracker” as the two most-watched shows in streaming alone.

CBS reported two other returns with double-digit audience gains. “Sheriff Country” reached a new series high in its second season, drawing 10.518 million viewers, 27% more than its series premiere last year. “NCIS” drew 10.59 million for its Season 24 premiere, up 23% from its season premiere last year.

Where CBS placed in the rankings

Without sports, CBS reported seven of the week’s top 10 series in live+7 multiplatform viewing across linear and streaming. The seven were:

• “Marshals”
• “Tracker”
• “60 Minutes”
• “NCIS”
• “Sheriff Country”
• “NCIS: New York”
• “FBI”

The broadcast-only tally placed eight CBS shows in the top 10. CBS added “Georgie & Mandy’s First Marriage” to the multiplatform list.

Title labeling differed within CBS’s own figures. Its broadcast ranking used “Georgie & Mandy’s First Marriage,” while the year-over-year growth table used “Georgie & Mandy’s First Wedding.”

CBS’s year-over-year table showed growth for several other programs:

• “NCIS: New York” reached 10.52 million, up 58% from the previous year’s time-period premiere for “NCIS: Origins.”
• “FBI” drew 8.93 million, an 18% increase.
• “Georgie & Mandy’s First Wedding” drew 8.70 million, up 11%.
• “Fire Country” reached 7.96 million, up 7%.
• “Survivor” attracted 7.94 million, up 13%.
• “NCIS: Origins” drew 7.75 million, up 19%.
• “Elsbeth” reached 7.69 million, up 5%.
• “The Amazing Race” drew 4.82 million, up 6%.
• “Harlan Coben’s Final Twist” reached 3.15 million, up 29%.

The “NCIS: New York” comparison measures a time slot rather than the same program. Its 58% gain came against the previous year’s premiere for “NCIS: Origins,” making the schedule comparison relevant but not a direct season-to-season measurement.

How much of the audience arrived later?

Among new series, “Cupertino” averaged 7.17 million viewers in live+7 multiplatform viewing. CBS compared that figure with 3.19 million viewers for live+same-day. The difference shows how delayed viewing can substantially expand a new program’s measured reach.

What does this change for CBS’s fall season?

The figures strengthen CBS’s claim that its schedule can attract broad audiences across broadcast and streaming. Seven multiplatform top-10 series, eight broadcast top-10 shows and substantial growth across established franchises support that claim.

“Cupertino” adds evidence that delayed viewing can shape audience measurement from the start. The results cover only premiere week, however, and do not establish whether CBS will retain these audiences after the initial launch period.
