In April of 1973, the first cell phone was finally complete. Doctor Martin Cooper had created the first portable handset and he was also the first person to make a call on a portbale cell phone. Ever since then, people have constantly been upgrading cell phones. Every year many new cell phones are put out on the market. Martin Cooper changed the world with his invention. According to the CTIA-Wireless Association, in 2007, 82% of Americans use a cell phone. The number has since gone up. That is huge! Now almost everybody you see has a cell phone. We can now do almost anything on our cell phones: text message, surf the internet, listen to music, play games, and talk to people. The cell phone has greatly evolved since its invention in 1973. We all owe Dr. Martin Cooper a lot of thanks, seeing how our cell phones are widely considered one of the most important things to have with you every day.
