What was the first TV series with an inter-racial kiss?

An inter-racial kiss on TV took place in 1964 between the characters Dr Mahler (Joan Hooley) and Dr Farmer (John White) on ITV's Soap Emergency Ward 10. This was in Britain.

A mention should go to William Shatner and Nichelle Nichols of Star Trek fame who on November 22, 1968 had an inter-racial black and white kiss in the episode "Plato's Stepchildren".

It isn't technically "inter-racial" but Lucille Ball (white anglo) and Desi Arnaz (white hispanic) kissed repeatedly in "I love Lucy".

Billie Thomas, who played "Buckwheat" on "Our Gang" had already kissed white girls, and such movies had been played on television before any other examples took place.
