Where 1200 fits
Why 1200 is special
At 1,200 baud text arrived faster than most people read, which is the threshold where a terminal session stops feeling like waiting. Bulletin board systems became practical at this speed.

Technology & computing
1,200 bps delivers characters faster than a person reads them, which is the point at which an interactive session stops being dominated by waiting. Bulletin boards and online services became viable there.
