MLB Steals Watch-Time, Impressions Leads During All-Star Week: TV By the Numbers
With insights from iSpot.tv & Vizio’s Inscape

Below is a snapshot of TV by the numbers for the week of July 18-24, highlighting the most-watched shows and networks using glass-level data from Vizio’s Inscape, and network and show TV ad impressions insights via iSpot.tv.
Most-Watched Shows and Networks
Via Inscape, Vizio’s TV data product with glass-level insights from a panel of more than 19 million active and opted-in smart TVs. Data is linear, live TV only and includes all episode types (new and reruns). Rankings are by percent share duration (i.e., time spent watching).
Major League Baseball’s All-Star Game fueled the sport to the No. 1 spot by watch-time during the week of July 18-24. Between late-week regular season games and Tuesday night’s all-star event, MLB collected 1.14% of minutes watched -- with half of that total attributable to the All-Star Game.
Some additional insights about the top programming on TV:
- Not included in those MLB totals is the Home Run Derby, which adds another 0.36% of watch-time.
- A lack of much live sports on the week gave rise to procedurals, which occupy five of the top 10 spots, led by NCIS at No. 2.
- Speaking of crime-related shows, Forensic Files soars week-over-week from No. 35 to No. 11 by minutes watched.
- Syndicated sitcoms also continue to be staples for audiences, with four such programs in our ranking this week, including week-over-week top 25 newcomer The Big Bang Theory (up from no. 36 to No. 23).
CBS leaps from No. 3 to No. 1 in our list of most-watched networks, thanks in part to the return of PGA action after a one-week hiatus. The network increased watch-time from 5.75% to 6.03% week-over-week, which was enough to retake the top spot.
Additional insights around the most-watched networks from the week:
- While SportsCenter made up over 24% of minutes watched on ESPN, it’s the MLB Home Run Derby’s one-off appearance that fueled much of the network’s week-over-week climb from No. 14 to No. 10 in our ranking.
- Hallmark Channel moves from No. 8 to No. 7 in our ranking week-over-week, as audiences tuned into syndicated airings of programs like The Golden Girls, Reba and Frasier (among others).
- TNT is the lone week-over-week newcomer in our ranking, via NCIS: New Orleans and a steady slate of superhero movies coinciding with San Diego Comic-Con over the weekend.
- Day One (Sunday) of Shark Week helped drive Discovery Channel up from No. 22 to No. 18 week-over-week, as audiences bit into the network’s shark-focused specials.
