When handwriting on a piece of paper, you should underline the title of an episode of a television show. Titles of episodes are typically treated similarly to shorter works, which are often underlined or put in quotation marks in typed formats.
Here's a quick summary of how to handle other options:
- The title of a television show: should be italicized (or underlined if handwritten).
- The name of a character on a television show: typically written in plain text, but can also be enclosed in quotation marks.
- The name of a channel a television show is on: written in plain text, often capitalized but not underlined or italicized.
