Frequency

The number of exposure opportunities required to convey a message to a desired audience or market. Frequency is often conflated with the term Effective Frequency. Effective Frequency seeks to report both the number of times a person must be exposed to a message before responding and the number of times a person must be exposed to a message before exposure is considered wasteful.

Over time the conflation has advanced a general definition of frequency – the optimum number of exposure opportunities required to effectively convey a message to a desired audience or target market.

Frequency was first clinically described by Hermann Ebbinghaus (January 24, 1850 — February 26, 1909) a German psychologist who instigated the experimental study of memory.
