Prvn\u00ed keyloggery se objevily v dob\u011b, kdy byly osobn\u00ed po\u010d\u00edta\u010de je\u0161t\u011b v plenk\u00e1ch. V 70. letech 20. stolet\u00ed americk\u00e9 zpravodajsk\u00e9 slu\u017eby experimentovaly s jednoduch\u00fdmi za\u0159\u00edzen\u00edmi p\u0159ipojen\u00fdmi k elektrick\u00fdm psac\u00edm stroj\u016fm, aby mohly sledovat, co se p\u00ed\u0161e.

V\u011bt\u0161ina keylogger\u016f m\u00e1 dnes podobu softwaru.

Krom\u011b softwaru existuj\u00ed tak\u00e9 hardwarov\u00e9 keyloggery. Nejjednodu\u0161\u0161\u00ed jsou mal\u00e9 adapt\u00e9ry p\u0159ipojen\u00e9 mezi kl\u00e1vesnici a po\u010d\u00edta\u010d.
