late noticing this but . . .
Late noticing this but a friend is an old fart musician, songwriter, and singer. His audience is old guard. He made two CD's after he retired from his day job, teacher and school principal. The first one sold well. The second batch of CD's burned for the second release six or eight years ago take up a lot of room in a spare bedroom. Can hardly give away the CD's but the downloads on the internet are still doing well.
Generally you have to do a pretty large run or pay a pretty high price per unit on pressed CD's or whatever you call the ones that are made pretty much instantly. A friend's business had a 20 CD or DVD burner, he didn't even use it to produce his own video's, too many bad copies from burning. He produced both entertainment and instructional video's, someone else that I don't think has any interest in hardcopy again. I know he ate a bunch too.
I think most of your demand for hard copies is lending library type entities, the clubs and such. Some from individuals but I doubt you sell a hundred copies to individuals if you offer hard copies and downloads.
Took some adjusting to pay fifty or seventy-five dollars for a book downloaded off the net but now I do it and in some ways prefer it to a hard copy. Can't search a hard copy nearly as easily. Does suggest one option though, you might offer the DVD and download for a slight extra premium than buying either one. I have bought both when offered that option sometimes. As mentioned, at this point I think downloaded software is as tough or tougher to copy than a disc, not that either is too hard if somebody wants to.
It's a fast changing market now. Should have held on to my eight tracks, they are starting to be worth pretty good money!
