A television episode is a single installment of a series that tells a part of a larger story. Each episode typically lasts between 20 to 60 minutes and can vary in format, including drama, comedy, or documentary. Episodes are often grouped into seasons, with each season containing multiple episodes that explore different themes or story arcs. Episodes can feature recurring characters and plots, allowing viewers to follow their favorite stories over time. They are usually broadcast on television networks or made available through streaming services like Netflix or Hulu. The success of an episode can influence the show's continuation or cancellation.
