The first matchup between Jaylen Brown and Jayson Tatum delivered a viewership pop in what has been a strong start to the NBA season.

The latest edition of NBC’s “Coast 2 Coast Tuesday,” featuring Celtics-Sixers in most markets and Thunder-Trail Blazers on the West Coast, averaged 4.4 million viewers on NBC across a Nielsen-measured linear audience and streaming data tracked by Adobe Analytics — the largest audience yet for NBC’s Tuesday night regional package, surpassing the previous week’s 3.7 million.

The telecast, which peaked with 4.7 million in the 8:45 PM ET quarter-hour, more-than-doubled the same week last year (Magic-Hawks or Thunder-Clippers: 2.0M).

NBC is now averaging 5.2 million viewers for its primetime games this season — a figure that excludes its Opening Day matinee between the Celtics and Pistons — up 37% from last year.

Now featuring Brown and LeBron James, the Sixers have figured prominently in what has been a strong start to the NBA season. Their game against the Pistons a week ago Wednesday averaged a 1.0 rating and 2.02 million viewers on ESPN, up 36% in ratings and 47% from Timberwolves-Knicks last year (0.7, 1.38M).

The Mavericks-Spurs nightcap averaged 0.8 and 1.56 million, on par with Spurs-Lakers a year ago (0.8, 1.56M). ESPN is now averaging 1.9 million viewers for the season, up 8% from last year and its highest average to start a season since 2015-16 (excluding the 2020-21 season that began Christmas week).

(Note that out-of-home viewing was not included in Nielsen estimates until 2020 or fully accounted for until 2025, that this is only in the second year of a new Nielsen methodology integrating “Big Data” from smart TVs, set-top boxes and first party data with its traditional panel, and that Nielsen has recently tweaked its measurement to better account for co-viewing of games.)

Last Friday night, Sixers-Cavaliers averaged a 0.9 and 1.82 million on Prime Video — nearly doubling Rockets-Spurs last year (916K). Blazers-Lakers led out with a 0.9 and 1.75 million, up 65% from last year’s Warriors-Nuggets (1.06M).

An updated average for Prime Video was not immediately available, but all six of its games have increased at least 50 percent in viewership.
