I recently was showing a client my libsyn.com stats. I explained how I had all of my “School of Podcasting Morning Announcements” poddcasts online. I clicked a button to jump to my earliest shows and I could see my first episode titled, “First Podcasts Always Stink” and I could see where it came out in October of 2005, and the last three months it's still getting downloaded. Here are my stats:
Total Downloads: 2693 (as of 11/27/12)
September 2012 – 109
October 2012 – 20
November – 17
I've always said people will go back and download your back catalog (even if it was seven years ago).
