These first-generation (1G) systems could support far more simultaneous calls but still used analog cellular technology. Early mobile phones required vehicle installation due to their size and power needs. Mobile phone technology has progressed significantly since its origins, evolving from large car-mounted systems to compact, handheld devices. These 0G systems were not cellular, supported a few simultaneous calls, and were very expensive. The advances in mobile telephony have been traced in successive "generations", starting with the early zeroth-generation (0G) services, such as Bell System's Mobile Telephone Service and its successor, the Improved Mobile Telephone Service. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries. The growth in popularity has been rapid in some places; for example, in the UK, the total number of gtspin casino mobile phones overtook the number of houses in 1999.
