1640s, "a spreading abroad (opinion, information, etc.) for acceptance," from Latin disseminationem (nominative disseminatio) "a scattering of seed, a sowing," noun of action from past-participle stem of disseminare (see disseminate). Or perhaps a native noun formation from disseminate. The figurative sense in English is earlier than the literal one of "act of sowing or scattering seed for propagation."
