The Simpsons went live in the US on Sunday (Monday New Zealand time).
The long-running animated sit-com - which was first broadcast in December 1989 - saw its episode on both the East and West Coasts of America end with a three-minute segment where Homer Simpson, who is voiced by Dan Castellaneta, answered fan questions.
In the introduction to the segment, Lisa Simpson (Yeardley Smith) quipped: "It only took us 27 years to do what they could do in 1954."
And Homer vowed the show will "never" end.
Seated behind a desk in "Fox's secret bunker", he said: "This is the last episode of The Simpsons. Just kidding, The Simpsons will never end."
