I frequently see discussions all over the web about what the first and last laserdiscs were...but I'm curious to see what people consider the first special feature.
I think the generally accepted answer are the special features on the Criterion releases of Citizen Kane and King Kong which were both released on the same day. King Kong features the first commentary and Citizen Kane contains various special features including a trailer.
But while I have been adding stuff to the wiki I came across
[You must be registered and logged in to see this link.] released in 1980. Not only is this one of the earliest "adult" laserdiscs it is also the earliest example I've found so far of different audio channels. The left channel contains a voice over explaining the massage techniques (I assume) while the right contains just music. By default both of these are turned on but either can be turned off.
Although not a commentary this could most certainly be considered a special feature.
You could go even further and say that chapter selection is a special feature in which case the earliest I've found so far is
[You must be registered and logged in to see this link.] released some time in 1979.
So what do people think? Even though we laugh at DVDs which list chapter and audio selection as special features, do they qualify for the earliest laserdisc special features? Have you found earlier examples or other, more interesting contenders for the title of first special feature?
I think the answer will be different for everyone, I personally think Touch of Love might have the title in my books, I just think it might be interesting to hear other people's opinions.
