If you felt that you have something to offer on a TV show or there are some things that happened recently that is newsworthy, you can find ways to be in front of a large audience and be on TV. When it comes to this, you have to let the TV people know that you will be good for them.
First, you should build a list of the TV shows you would like to appear. You can search online for shows you watch. Narrow down your search to topics that are similar to yours. Put a pitch together and take into consideration what would make you guest experience special. You can also draft your biography. Compile articles written about you and a short and comprehensive biography as well. This well also serves as your press kit.
Look for a publicist who could make introductions on your behalf. There are those who charge per booking but many want upfront payment. Start emailing, mailing and calling. Practice diligence when getting in touch with the shows you like to appear. Follow up booking agents through phone calls. When you have booked something, make sure that you are prepared. Take into considerations all the questions they might ask and your response.
