One thing that helps any Inventor with a product is media exposure. The trick is getting the media interested in you and your product. The right exposure can have a two-fold success. The first is everyone now knows about your product and wants to buy it. The second is you are now known as an Inventor with a product. This exposure can draw other companies to you looking for ideas for products that fit their line.
Contact your local cable network and find out if you have any local shows you can be on as a guest. Local shows are always looking for guests. Contact your Public Radio Station near you. They want on-air guests. The great thing with them is they rerun interviews a lot to fill air time. I did an interview with NPR that they ran for 5 months at various times of the day.
Contact your state paper for an interview for the Features section. Try submitting a Press Release to magazines that fit your target market.
Your local T.V. station can be a great asset. Talk with them about using you as a local expert they can contact for a quote when they run stories on inventions.
If you have local small press newspapers that are free giveaways to the public see if they want an interview. Contact your small business group in your area for other exposure opportunities.
Get t-shirts with your website and product on them. Send some to the national radio shows. John Boy and Billly is a nationally syndicated radio show that is popular in my area. I sent them two t-shirts. They talked about my website for 3 minutes on air. They have a 10 million listening audience. I got 67,000 hits within 5 minutes of them mentioning me on the air. It cost me two t-shirts. Well worth the investment.
There are numerous ways to get exposure for free. You just have to be creative in your thinking. Use the same energy that helped you create your invention to get it noticed.
