When Star Trek was created in the 1960s, many of the themes that were discussed were extremely controversial, especially communism and interracial relationships. In fact, the first interracial kiss on television, occurred on Star Trek Original Series, during a time when racism was high and the Civil Rights movement was in full force.
What many people do not know is the fact that the actress who played Lt. Uhura, Nichelle Nichols did not plan on staying with the television show into the second season. She had a little visit from a very influential man at that time: Martin Luther King, Jr., who convinced her to stick with it. It was the only television show that he and Ms. King would allow their children to watch, because it had a strong, black woman, and he believed she was a role model for his children.
So, the lesson here: Martin Luther King, Jr. was a trekkie! But seriously, Star Trek opened up the door for what the future could possibly hold: equality. And so far, for the most part, that future has been realized. I wonder how many other social possibilities will be realized in the future that were ‘predicted’ by the Star Trek series.
