Amenities offered have also changed, with motels that once touted color television as a luxury now emphasizing wireless Internet, flatscreen television, pay-per-view or in-room movies, microwave ovens, and minibar fridges in rooms which may be reserved online using credit cards and secured against intruders with key cards which expire as soon as a client checks out. Many independent motels add amenities simply to remain competitive with franchise chains, which are taking an increasing market share. Long-time independent motels which join existing low-end chains to remain viable are known as "conversion" franchises; these do not use the standardized architecture which originally defined many franchise brands.
