Since the beginning of major league baseball there have been six eras. Starting with the Pioneer Era, 1880-1892 moving on to the Deadball Era, 1893-1919. The next era is the Landis Era, or Lively Ball Era, 1920-1946. After WWII there was the Baby Boomer Era or Integreation Era, 1947-1968. With the introduction of artifical grass we have the Artifical Turf Era, 1969-1992. Followed by the Camden Yards Era 1993 to today.
