There are a lot of websites discussing how to obtain an appropriate software for your podcast. However, once you have your podcast ready it is time to publish it. Here there are at least a few possibilities how to do it:
• If you have a website or a blog, you can simply upload your podcast. This is the most obvious things to do. Check out however how much data you are allowed to store. That is because audio files are usually quite large, so you might soon run out of bandwidth and your listeners will no longer be able to listen to your podcasts. You may also have your hosting account blocked if you use too much bandwidth.
• Find a podcast hosting service that is either free or does not cost too much. Believe me, there are services which will not charge you a lot. They will be especially helpful for you if you do not want to host a podcast on your own blog or a website. I cannot recommend you any podcast hosting services, but you can try to Google it.
Overall, you should remember that the popularity of podcasts is growing, and that they may become very popular in the upcoming years.
