File:1992 NBC Promo (The Cosby Show Series Finale)

Description
(c)1992 NBC Universal/Comcast

And now for something I would have had sooner; but had misplaced the tape and didn't realize I have found it again until recently.

Anyway, this promo is for the April 30, 1992 2-part final episode of the Cosby Show ("And So We Commence"); beginning with a reference to the series being effectively the crown jewel in NBC's 1980s comeback from worst to first.

With April 30 ending up becoming the 2nd day of the Los Angeles Riots over the clearing of the cops involved in the incident with the Rodney King arrest; on NBC's Los Angeles station KNBC, Bill Cosby attempted to cool things off by asking the rioters to settle down and watch that last episode (which in the original airing also had NBC do a three-minute thank you).
