The 40th Primetime Emmy Awards were held on Sunday, August 28, 1988. The ceremony was broadcast on Fox from the Pasadena Civic Auditorium in Pasadena, California. The ceremony was held earlier than its traditional September date to avoid conflict with the 1988 Summer Olympics in Seoul, South Korea. Cable stations HBO and Showtime received their first major nominations at this ceremony.
Despite a season that consisted of only six episodes, newcomer series The Wonder Years won Outstanding Comedy Series. After winning his fourth consecutive Primetime Emmy Award for Outstanding Supporting Actor in a Comedy Series, John Larroquette requested to have his name taken off of the ballot for future ceremonies.
