Hello everyone! I am writing a biography on a favorite chef of mine and am having a hard time with the grammar. Can you help?

One of the things I'm stuck on is how do I write the name of a TV show? Do I quote it? underline it? italisize it?

Or, would anyone who is a great writer be willing to proof read it? It's always good to have a few sets of eyes look at it. If so, I can e-mail it to you. It's due tomorrow (Monday).

Thanks in advance.
