Given a reference text about the Tampa Bay Buccaneers, how many Super Bowls have they won.

Context: The Tampa Bay Buccaneers are a professional American football team based in Tampa, Florida. The Buccaneers compete in the National Football League as a member club of the league's National Football Conference South division. The club joined the NFL in 1976 as an expansion team, along with the Seattle Seahawks, and played its first season in the American Football Conference West division. Prior to the 1977 season, Tampa Bay switched conferences and divisions with Seattle, becoming a member of the NFC Central division. As a result of the league's realignment prior to the 2002 season, the Buccaneers joined three former NFC West teams to form the NFC South. The club is owned by the Glazer family and plays its home games at Raymond James Stadium in Tampa.

The Buccaneers have won two Super Bowl championships and, along with the Baltimore Ravens, are the only two NFL franchises who are undefeated in multiple Super Bowl appearances. They were regarded as a perennial losing franchise for most of their first two decades due to suffering 26 consecutive losses in their first two seasons and 14 consecutive losing seasons from 1983 to 1996. Despite these early struggles, Tampa Bay is the first post-merger expansion team to clinch a division title, win a playoff game, and host a conference championship; feats they accomplished by their fourth season in 1979. The team's image improved by the time of their first championship in 2002, also the first for a franchise built after the merger, but they would not win another playoff game until their second Super Bowl championship season in 2020. Concurrent to the lack of success outside of their Super Bowl wins, the Buccaneers hold the NFL's lowest winning percentage at.404.

Answer: The Buccaneers have won two Super Bowl championships.
