The TV show "Dynasty" was about which family?

Outside of flux capacitors, Game Boys, Walkmans, and the artificial heart, primetime soap operas were one of the most important parts of the 1980s.

Set in the glamorous world of Denver's oil elite, the show followed one ridiculously rich family as they schemed, married, divorced, and occasionally pushed each other into lily ponds. What family name appeared on those mansion mailboxes?
