A "home theater in a box" (HTIB) is a common name for a relatively inexpensive integrated home entertainment package, usually including a DVD player, surround sound capability, and a radio tuner in one box. While they lack the features of a custom-assembled home theater system, HTIBs are an inexpensive (and generally space-efficient) way to take advantage of the surround sound capabilities of the DVD format. They are manufactured by most makers of consumer electronics; Bose in particular markets their integrated home theater systems especially aggressively, though other traditional manufacturers such as Sony, Philips, and Panasonic market systems that tend to be considerably cheaper.
