The Detroit Lions franchise was founded in Portsmouth, Ohio as the Portsmouth Spartans and joined the NFL on July 12, 1930. Amid financial struggles, the team was relocated to Detroit in 1934. The team was also renamed the Lions in reference to the city's Major League Baseball (MLB) franchise, the Tigers.
The Lions won four NFL Championship Games between 1935 and 1957, all prior to the Super Bowl era. Since their 1957 championship, the team has won only a single playoff game in 1992 and never advanced beyond the NFC Championship Game. They are the oldest NFL team to not appear in the Super Bowl, as well as the only franchise operational for the entirety of the Super Bowl era and the only NFC team not to appear.
