For linear TV, we’ll often look at Live +0 Day, also referred to as “Live +Same Day,” which includes the households watching during a program’s initial airing until 3 a.m. local time the following day.
Now, with viewers having so much more flexibility deciding when to watch, we often look at longer stretches of time. This accounts for time-shifting, people who may watch later, or on demand. We also look at longer time periods to get a wider view on how viewership stacks up over a weekend or within a week or even longer. This can be valuable, especially when considering streaming programming that people watch on their own time at varying paces.
