Yeah, the "first interracial kiss" thing is largely a myth--or at the very least comes with a lot
of asterisks. More like "first interracial kiss between an African-American and a Caucasian on a scripted, prime-time, American TV drama." Excluding British shows, soap operas, variety shows, etc.
Still a milestone, no doubt, but it's "historic" status has been a bit inflated over the years--and everybody tends to downplay the fact that Kirk and Uhura were being forced
to kiss each other, while struggling mightily to avoid doing so!
