What is the secret to obtaining an interview on Oprah or any of the other top TV programs?
Working hard at your basic publicity and building recognition for yourself and your book. Many of the top interview programs far prefer to find their subjects on their own (they have scouts constantly looking for the talent they want), and generally respond negatively to pitches. You may want to retain the services of a broadcast publicist to help you appear on some of the many other shows that are not quite as demanding. There will be lots of information on this in the blog and in the book.
