The chances of major outlets—and particularly TV networks—bringing on an unknown, self-published author are slim to none. Sorry.
No matter how brilliant your book may be, or what other people selling product on social media may tell you, if you don’t have PROOF that you’re are an engaging, informative, entertaining guest who is not going to freeze when millions of people are watching, they’re NOT going to bring you in. There are too many other reliable, proven options available and network TV producers’ very livelihoods are hanging in the balance every single day. Their ratings are everything.
So, save yourself the trouble of filling out the ‘Contact Us’ form over at Good Morning America and focus first on the media you’re much more likely to get—local media.
