Kauffman originally pitched Friends as a show about "that special time in your life when your friends are your family" to then-NBC president Warren Littlefield shortly after their short-lived sitcom Family Album was canceled by CBS. Inspired by their own experiences as young adults living in New York City, the writers loosely based the six main characters on some of their own friends and family; Monica is based on Kauffman herself. Observing that each main character was originally written as a "one-note stereotype", Jonathan Bernstein of The Daily Telegraph identified Monica as the group's "uptight fun-killer". When Friends first aired, the majority of its earliest episodes revolved around Monica, via whom each character appears to be interconnected; Friends stars the character's brother, her best friend, her former roommate and her two neighbors socializing in Monica's apartment. In the pilot, Monica is dumped almost immediately after sleeping with her new date Paul on the night of their first date. Monica is tricked into bed with him after Paul lies to her about his sex life, falsely alleging that he has not slept with anyone in the two years since his wife left him. At first, NBC executives worried that audiences would react to Monica's role unfavorably, thus they decided to survey the studio audience and ask them whether or not they thought that having Monica sleep with someone on their first date made her character too promiscuous. Don Ohlmeyer, then-president of NBC's west coast division, was particularly adamant about his stance against Monica's role in the pilot, which he considered "casual sex". Kauffman recalled Ohlmeyer specifically expressing that Monica deserved to be dumped, a statement by which the writer was greatly offended, dismissing Ohlmeyer as a misogynist. Ultimately, the results returned in favor of Monica; audiences liked the character nonetheless, and the episode aired unchanged. Early in the series, Monica's apartment is established as one of the show's two primary locations. In the pilot, the apartment number is 5, which was changed to 20 in subsequent episodes after the writers determined that Monica actually lived on a much higher floor. Season three's "The One Where No One's Ready" takes place entirely in Monica's apartment because the show's budget was not large enough to accommodate additional sets or guest stars at that time. In the series finale, Phoebe certifies that each character shared Monica's apartment at least one point during their lives.
