Choose any particular era below and discover a time line of famous firsts related to virtually every facet of the game. Exact dates are listed where it's possible and new firsts are added to each era on a regular basis. Most Major League records are not listed here as they are not truly the first — they are simply better than the last one and modern team names are shown in their first year versus their previous names used in prior years. Baseball Almanac has covered the centuries, the home runs, the salary levels and much more in this unique look at baseball history through its famous firsts.
