"Big" is introduced as a wealthy man who runs into Carrie on the street, helping her pick up a large number of condoms that fell out of her purse after it had been knocked from her hand. He later spots her at a party, and after waving to her at the beginning of the evening, he later gives her a ride home in his limo. Their relationship runs the length of the series. At the start, she is intimidated and awed by him, and immediately gives him the nickname "Mr. Big". However, eventually Carrie and Big share a friendly and often passionate intimacy, yet he remains (in producer Michael Patrick King's words), "always slightly out of reach." Mr. Big's name is never mentioned until the last episode of the final season, where it is revealed to be John via Carrie's cell phone caller ID. His full name is finally uncovered in the first movie as John James Preston.
