Video taped lectures
My historical reflections on the early 1990's: there were regular late night TV broadcasts for professional development from the Royal College of Nursing. As part of my Nursing professional development I used to tape them on VHS and then watch them while I completed the workbooks and readings provided in the professional journals. I played, paused, rewound to my hearts content! I only recently threw the tapes and workbooks out. Those old TV recordings were something else!
