The market for replacement parts, accessories, or modified components for products after their initial sale.
Compound of 'after' (Old English æfter) and 'market' (Old English market, from Latin mercatus meaning commerce). Developed as business terminology in the 20th century to describe secondary markets.
The aftermarket is huge—often as valuable as the primary market itself—which is why car manufacturers sometimes resist third-party parts makers, and why your phone charger isn't made by your phone company! It's a battleground for profit.
