Here's why:
* They are considered proper nouns. Like names of people, places, and organizations, they are capitalized.
* Style guides generally recommend italics for titles of longer works. This includes books, movies, television shows, and albums.
Examples:
* The Office (not "The Office")
* Breaking Bad (not "Breaking Bad")
* Game of Thrones (not "Game of Thrones")
Exceptions:
* Some publications may have their own style guides. Always check the specific guidelines if you are writing for a particular magazine or website.
* If you are writing about a specific episode title, then it should be enclosed in quotation marks. For example: "The Office" episode "Dinner Party."
