A longbox is a form of exterior cardboard packaging for musical compact discs in widespread use in North America in the 1980s and early 1990s.
Longbox packaging was phased out in the early 1990s due to the controversy. At the same time, major retail stores were no longer selling vinyl records and had converted their displays to accommodate shrink-wrapped jewel cases, meeting the rising consumer demand for CDs while eliminating the need for longboxes.
Some merchants resisted this discontinuation, as longboxes theoretically made it harder for shoplifters to hide the items. Several proposals for new types of packaging that served the display-size of the longbox and theft-prevention goals were developed. A common replacement consisted of locking plastic frames (security keepers) containing anti-theft detection strips, designed to roughly meet the same dimensions as the longbox to fit into the same racks in a record store, and removed by the cashier upon purchase. Eventually, as LP-sized sales racks were phased out, these frames were reduced to a size only slightly larger than the disc boxes themselves.
Aside from the occasional box-set or vanity CD packaging, longbox packaging is largely obsolete. However, longboxes are still occasionally used by warehouse clubs such as Costco for both CD and DVD packaging, though the boxes are typically generic and not produced by the media distributors.
Most original longboxes were discarded upon purchase, and they have since become desirable amongst music collectors. A compact disc is worth more if it is accompanied by its original longbox.
