introduce [someone] to [activity / subject / idea]

用法筆記

Always followed by 'to' when specifying the activity, subject, or idea. The subject can be a person, an institution, or an experience itself. This sense differs from sense 2 (FIRST MEETING) because here the object experiences an activity or field of knowledge, not another person.
