Invented by Alexander Graham Bell in 1876, the telephone has changed significantly since then with mobile devices being ubiquitous in the 21st century and these devices including numerous other functions besides voice communication. In 2014, the telephone is a complex means of communication, featuring Internet connections, cameras and countless applications.

The first telephones that became popular at the end of the 19th century were called candlestick phones and featured a mouthpiece and a receiver. The next models included rotary dial phones, popular in the first half of the 20th century, followed by push-button telephones introduced in 1963 and portable phones introduced in the 1980s. After 2007, smartphones became popular all around the world.
