What makes their use of CGI "revolutionary" is how it enabled them to have a real quick production schedule. Most episodes are written, acted, and animated in the span of 6 days. They will often sketch out ideas for the season beforehand, but the bulk of the work on a given episode is done in that very short timeframe. It's why their show is always able to be incredibly topical, often lampooning current events within days of hitting the news cycle. Personally, I think it's the reason they still feel fresh and relevant even after more than 20 seasons. Traditional animated sitcoms like The Simpsons or Family Guy still contend with a 9-12 month production schedule per episode.
