Episode 3
In short
The third instalment of a television series or podcast broadcast on this date.
In plain words
It is the third part of a story told in chunks. Viewers watch or listen to this specific segment to continue following the plot.
A simple example
After watching the first two parts of a mystery show, you tune in to Episode 3 to find out who the main suspect is.
Why it matters
It builds the narrative and keeps the audience engaged. Without it, the story remains unfinished and confusing.
Easy to mix up
Do not confuse this with a season, which contains many different episodes.
