This topic may even predate Mr. Swinson (gasp!).  According to 
WikiPedia, the predecessor to the telecine was the kinescope which 
basically recorded a TV image to film (at video frame rates) so that 
it could be re-played into a video camera for TV re-broadcast.  This 
did not support the 2:3 pulldown that 24 fps cinematic film required 
for proper presentation as TV video.  The original telecine produced 
analog video rather than the digital output most commonly used today. 
It seems that the key features that the telecine introduced was 
support for 2:3 pulldown for 24 fps as well as transfer direct from 
film for the best quality.
