Turner Classic Movies (TCM) only shows top-notch classic films. They have been the guardians of classic cinema, and the only 24-hour network that focuses on classic movies. Robert Osbourne is the long standing host and represents TCM but there are other great hosts, guests and movie starts that give you a brief synopsis and critique of each film before showing so you learn a little about the flick you watch.
See the dawn of motion picture and relive some classics on TCM. Those days are long gone, but TCM keeps the classics alive.
