Mobile phones have changed a lot over the years. The first mobile phone was invented by Martin Cooper in 1973. It was large, heavy, and very expensive. Only a few people could use it.
In the 1990s, mobile phones became smaller and more affordable. People used them mainly for calling and sending text messages. Later, smartphones were introduced. In 2007, Apple Inc. launched the first iPhone, which changed the mobile phone industry.
