1982 by the laptop manufacturer GRiD (who had the patents on the idea at the time) for their Compass model. In 1983, the laptop used a modern clamshell design. The first Motorola model to support the clamshell design was the MicroTAC, created in 1989, although General Telephone & Electronics held the trademark from the 1970s for its Flip-Phone (one of the first small handheld electronic phones), until 1993. Flip phones became popular in the late 1990s and this factor lasted until the early 2010s. The clamshell form factor began to experience a decline in popularity in the late 2000s and early 2010s, due to the increasing popularity of touchscreen smartphones such as the iPhone, which use a slate-like form factor and large, non-folding screens. Clamshells remain a predominant form factor for feature phones—which remain popular among specialized audiences who prefer their simplicity or durability over smartphones. Samsung also released a low-end smartphone in South Korea known as the Galaxy Folder, which has a flip phone design and keypad reminiscent of feature phones whilst running Android. In 2019, a new trend of foldable smartphones using rollable OLED displays began to emerge: the Samsung Galaxy Fold uses a clamshell form factor with a vertical fold and a small secondary screen on its cover, and exposing a larger, tablet-like screen when opened. Motorola unveiled a reimagining of the Motorola Razr in November 2019, which uses a foldable display and a clamshell design reminiscent of its namesake line of feature phones. Automotive In automotive design, a clamshell bonnet or clamshell hood is a design where the engine cover also incorporates all or part of one of the wings (fenders). It is sometimes found in a car with a separate chassis such as a Triumph Herald or in cars based on a spaceframe where the bodywork is lightweight and carries no significant loading, such as the Ford GT40 and Ferrari Enzo, where the whole rear end can be lifted to access the engine compartment and suspension system. It is also sometimes seen in unibody cars, albeit much more rarely - such as the BMW Minis and Alfa Romeo GTV. It is also an informal name for General Motors full-size station wagons, manufactured from 1971 to 1976, that featured a complex, two-piece "disappearing" tailgate, officially known as the "Glide Away" tailgate.
