[QuadList] Johnny Carson clips

[Dennis Degan]

		I previously offered:

> I don't know what clips were seen, but the Tonight Show was recorded on quad only up to 1981.  That's when the show began stereo audio production, thanks to Ron Estes.  He actually pushed for stereo recording before the network was ready to air the show in stereo.  Stereo MTS broadcasting did not begin until 1984.  The Tonight Show was the first TV program to air in MTS stereo:  http://www.tvtechnology.com/opinions/0087/remembering-tv-stereo-pioneer-ron-estes/183149

> Dennis, did they go to MII at that point?  I know we had stereo Ampex quad machines in the early to mid 80s.  I am assuming that NBC was all RCA back them, but I have little experience with those.

		I answer:

	No, the stereo show was recorded on 1-inch Type C.  NBC had both RCA and Ampex quad VTRs, both in New York and Burbank.  When 1-inch was introduced at NBC-New York in 1978, the machines were Sony BVH-1000s.  The MII format was introduced around 1985 or so.  Here are two photos of the first two Type C machines, as they were being installed at 30 Rock:  http://www.flickr.com/photos/dennisdegan/515355785/  http://www.flickr.com/photos/dennisdegan/515328974/
