Smart Phone

Fifteen years ago, many people were still coming to terms with learning how to use a basic mobile phone to send texts with a few select models having very limited and slow internet access. The concept of an appliance with phone and computer features was patented by Theodore G. Paraskevakos in 1973 but it lay dormant for over two decades. Some toyed with the use of the palm top computer to organise their lives but the first smartphone actively marketed was manufactured in 1999 by Japanese company NTT Docomo. In 2014, 90% of handsets sold are either Android or Apple with over a billion smartphones now in usage.
