What is so good about Matt Groening's Satire that has kept him around till today???

Matt Groenings "The Simpsons" has been around for decades now and is by far one of the most successful Televison series in the history of animation. I decided to look up what Matt himself actually had to say. One of the things I gathered is from the video above is what my Lecturer on Character design and storyboard development also said. And its to do with how recognisable his characters are just based on the shapes of their sillouettes, making The Simpsons redundant (easily identifiable). Lets face it, The Simspns are a lovable representation of what the average plutonic American family could be like on a day to day basis. Lastly, its easily watchable for the whole family, even though its a cartoon, adults can watch it due to the adult humour, but in saying this, the type of humour is not too raw for young children.
