Final answer:
The television slot from 11:00 P.M. to 11:30 P.M. Sunday through Saturday in the eastern and Pacific time zones is commonly known as 'late news.'
Step-by-step explanation:
In the context of television scheduling and dayparts for eastern and Pacific time zones, the slot between 11:00 P.M.-11:30 P.M. from Sunday through Saturday is typically referred to as late news. This timeslot is when many local stations schedule their last news program of the day, recapping the day's events and providing late-breaking stories before the transition to late-night programming.
This slot is crucial for catching up on the day's events and is especially important in the realm of politics, as news during this period can capture last-minute developments. Late fringe refers to the time slot after prime time and before late news. It is typically the final time slot of the day for network programming.
