There are a few exceptions to this rule. For example, if a TV show title is written in all lowercase letters, then it should not be capitalized. Additionally, if a TV show title is part of a sentence, then it may not be capitalized if the sentence is not a title itself.
Here are some examples of how to capitalize TV show titles:
* The Simpsons
* Game of Thrones
* The Big Bang Theory
* The Walking Dead
* Saturday Night Live
Here are some examples of when not to capitalize TV show titles:
