I'm not sure, I'm just guessing they've been on air for 20 years (including the very early episodes that Matt Groening drew that aired on the Tracy Ullman show in the late 80's) because the promo spots on TV says the movie was 20 years in the making. I don't however believe it was actually 20 years in the making, more like 3-4 years.
The producers and Matt did however consider making a movie during the early seasons (they said so on their commentaries for certain episodes on the DVD boxsets) but it was put on the backburner for long time until it was picked up again in the early 2000's.
