I still have - and use - several VHS tapes, so I just went to have a look. It seems the oldest ones are Callanetics (which I don't use) from 1991 and 1992. The FIRMs are from the mid 90's, and there were a few with no copyright date: Karen Voigt's Your Personal Best, Cathe's Mega Step Blast, and another one that at least had an email address on the case, so I'll assume it's not *too* old
. All the others seemed to hover from around the turn of the century
