How Modern Baseball Spread

In an ongoing effort, baseball researchers are documenting when baseball first reached areas within and beyond the United States. This display shows current data on the historical dissemination of the game. By adjusting the "sliders" below the map, you can trace the extent of spread for any year.

The map shown below has a pin for each locality with an early game or club. You can zoom in, zoom out, and (by "grabbing/dragging" the map) change the area you want to focus on.

Each pin allows you to reveal the data its placement is based on. To find details for a town or area of interest to you:

  • Zoom in to the area of interest
  • Click on a pin you think represents your target area. A balloon will open stating the number of games/clubs found there.
