I was listening to an older episode (2012) of "The Audacity to Podcast", where the host is talking with a copyright/IP Lawyer: https://theaudacitytopodcast.com/tap077-copyright-laws-for-bloggers-and-podcasters/
I am not a lawyer (and if I should take this to Law.SE, I'll do that, too (or instead)), but I just want to verify something I believe he said, and also to make sure that it's also still true, as I know things can change, but the common wisdom stays the same.
First, I do know that since 1978 or so, everything one "fixes" into a specific form (photo, poem, story, essay, podcast episode), automatically has a copyright.
But he said it's less defendable if it's not registered -- a registered work often will get lawyers to take on a legal case for infringement based just on anticipated rewards.
Since registration is about $35/an instance, he recommended registering things in "groups" - AND he said that you had to file the registration within 90 days of publication. In other words, file a quarterly "portfolio" of all blog posts or podcasts episodes created in the last 90 days, no matter how many items are in it.
(Again, I know the works are technically protected just by existing, but I want to be able to defend my works easily, if desired. I would love classes to play my grammar writing podcasts to explain a concept, or for teachers to recommend episodes as supplements, but I want to be able to keep, say, a textbook publisher from just using my transcripts without permi$$ion.)
Question: Do you really have only 90 days from publication/posting to register copyright with the LOC? (I was hoping for annual - quarterly is so frequent!)
Question2: Do I have to say "copyright 2019 (my name)" in each podcast, or is having it written in the notes sufficient? (I am aiming for under 5 minutes per episodes, so I don't want to use airtime for anything extra. I've really honed my opening to name the podcast, me, the episode to be a single short sentence.)
