In general, titles of longer works such as books, movies, television series, and albums are italicized, while shorter works such as articles, songs, and short stories are usually placed in quotation marks.
Based on this guideline:
- The television series titled Adventures of Rin-Tin-Tin (italicized)
- An article in a newspaper titled "Who is Rin-Tin-Tin?" (in quotation marks)
- A country music song titled "Me and Rin-Tin-Tin" (in quotation marks)
- A short story titled "An Ode to Rin-Tin-Tin" (in quotation marks)
So, only the television series title should be in italics. The others should be in quotation marks.
