This topic's been batted around here now and then, but I was reading up on it so I thought I'd share: July 1964 ITV's British prime time soap Emergency Ward 10 shows a kiss between black and white actors (a photo of which appears on this site). December 11, 1967 NBC airs the TV special Movin' With Nancy, in which she shares a kiss with Sammy David Jr., albeit it looks like a cheek kiss next to the mouth (go to about 4:50 in this clip to see Nancy and Sammy smooch). Sept. 29, 1968 CBS airs the 1st episode of season 3 of The Smothers Brothers Comedy Hour, in which the Bonanzarosa sketch features black football star Rosie Grier, in drag, planting a smooch on the forehead of Harry Bellafonte, and then on Cass Elliott (dressed as a man). (Go to 8:20 in this clip to see those smooches.) November 22, 1968 NBC airs the Star Trek episode "Plato's Stepchildren", in which Captain Kirk is forced to kiss Uhura (see 3:13 in this clip). So, Britain beats Trek to it by almost 4.5 years. Discounting that, we have at least two kisses, albeit not on the lips, on US TV prior to Kirk and Uhura were portrayed kissing on the lips. But then it appears it's a fake kiss, like a fake punch (and Shatner says it is). So, what's the real first interracial kiss on US TV? I guess it's all a matter of opinion.
