What is the difference between a podcast and a recording of a conference call? Quick answer: there isn't a difference. Longer answer: one way to look at it is a podcast is just your recorded audio conference call that's been "published."
And that's really all there is different between the two. Has someone mentioned that it would be a good idea to make podcasts for the company; that it would be good advertising? Have you had a brainstorming meeting to come up with podcast material? Has someone been put in charge of making the podcast program happen? (Was it you?)
Here's the good News then: if your company has been doing a lot of conference calls, then there's a good chance you already have a bunch of podcasts just waiting to be published! Because what could be better content for a company podcast than its presentations about its products, industry News, or the exciting things happening there.
With content taken care of, it's time to edit and transform the conferences into podcasts. Using a standard audio editing program, you can add the company jingle to the beginning, a few words from the CEO, or a general introduction. Snip out long silences as well as any proprietary or secret information. At the end, you can add a conclusion, contact info, product discounts, music, or just let the ending of the presentation be the end of the podcast. It's entirely up to you.
For publishing, you can simply add it to your website, and do an email and Twitter campaign to promote the new "Podcast section." You can also upload it to YouTube, or even iTunes! The point is to get your podcasts out there and working for your company 24/7.
After all, a really great presentation shouldn't be heard just once.
