The strip's situations and characters were influenced by the pioneering soap opera strip Mary Worth as well as Rona Jaffe's bestselling 1958 novel The Best of Everything. The three main characters are Margo Magee, a brunette who has variously held positions as a secretary, actors' agent, publicist and event planner; Abigail "Tommie" Thompson, a redheadednurse; and Lu Ann Powers née Wright, a blondeart teacher. The appearances of the three main characters were loosely based on real actresses: Tommie was based on Lucille Ball, Margo on Joan Collins and Lu Ann on Tuesday Weld. Kindly neighbor ProfessorAristotle Papagoras serves as a father figure. Lu Ann, originally single, met and married a U.S. Air Forcepilot named Garth Powers in 1964, after which she moved out of the apartment. She was replaced by another blonde, Beth Howard. Lu Ann's husband was later killed in Vietnam and she eventually moved back into the apartment, while Beth was written out after falling in love with young physician Lester Pride. There have been a number of other notable supporting characters in the comic strip throughout the years. Byron Frost was Margo's generally supportive boss from 1962 to 1990. Newton Figg, the handsome but childlike author of children's books, talked to his pet stuffed animals as though they were real. Not surprisingly, he had some romantic challenges. Roberta Magee, Margo's temperamental mother, caused recurring troubles. When Lisa Trusiani took over scripting the strip, stories began to revolve more around family relations. Gabriella Gatica turns up in 1999 as Margo's biological mother, a maid that Margo's father had had an affair with. Blaze Wright, Lu Ann's employment-challenged cousin and an aspiring actor, first appeared in 1998 and appeared off and on through 2011. Ruby Wright followed in 2007 and turned out to be Lu Ann's biological mother. Eric Mills, owner of the Mills Gallery, nurtures Lu Ann's interest in painting; he also became a reoccurring romantic interest for Margo in 2006-2008 and in 2014-15.
Alex Kotzky, who drew and inked in a tight and crisp realistic style, was the artist of Apartment 3-G for more than 30 years. When Dallis died in 1991, Kotzky began writing the strip. With Kotzky's death in 1996, his son, Brian Kotzky, took over as the Apartment 3-G artist, and Lisa Trusiani became the scripter. In 1999, Frank Bolle stepped in as the illustrator when Brian Kotzky left to become a teacher. Writer Margaret Shulock later succeeded Trusiani. Dallis, formerly a psychiatrist, also created the soap opera comic stripsRex Morgan, M.D. and Judge Parker.
