Neverending Television

Nova, 1974
America's longest running science show, Nova has run on PBS for 35 years. Never limiting itself to hard or soft science, producers will literally do a show on anything, which is sort of what has made it so watchable decade after decade. It does not shy from cheesy re-enactments, however, hence this picture above, of 19th-century inventor of the vacuum flask James Dewar, and his assistants.
