The above video provides a neat little (five minutes) history of the laugh track. I agree with all of the points made by the, er, maker and I’d like to write more than these two sentences, but I can’t. You see, I actually did write more but then my word program mysteriously erased everything and I’ve got to be somewhere in five minutes. Enjoy the video–it’s self-explanatory. Wait, make that three sentences. Wait make that four sentences…etc
