Wife acceptance factor

Wife acceptance factor, wife approval factor, or wife appeal factor (WAF) is an assessment of design elements that either increase or diminish the likelihood a wife will approve the purchase of expensive consumer electronics products such as high-fidelity loudspeakers, home theater systems and personal computers. Stylish, compact forms and appealing colors are commonly considered to have a high WAF. The term is a tongue-in-cheek play on electronics jargon such as "form factor" and "power factor" and derives from the stereotype that men are predisposed to appreciate gadgetry and performance criteria whereas women must be wooed by visual and aesthetic factors.
History.
Larry Greenhill first used the term "Wife Acceptance Factor" in September 1983, writing for "Stereophile" magazine, but Greenhill credited fellow reviewer and music professor Lewis Lipnick with the coining of the term. Lipnick himself traces the origin to the 1950s when hi-fi loudspeakers were so large that they overwhelmed most living rooms. Foreman suggested that audiophile husbands should balance their large and ugly electronic acquisitions with gifts to the wife made on the basis of similar expense, with opera tickets, jewelry and vacations abroad among the suggestions.
