Definitely contact your local television stations. Find out the name of the producer who arranges author interviews, or the reporter who covers the subject that you've written about. Don't forget cable television. As you're mailing and faxing to radio stations, newspapers and magazines, pay particular attention to your local media. Writers always have a better shot at appearing in one of their local papers, or on a local station than across the state or in some other state.
Most cities have a plethora of small, sometimes free, community newspapers.
These papers are often hungry for material, especially if that material is for free. For several reasons you don't want to send your book. You will miss some prospects if you make them do too much work. Be sure to include Today, Good Morning America , CNN , and other similar programs. Call your friends and let them know that you are available.
