On April 3, 1973, Martin Cooper made the first call on a mobile phone, beginning what would become a technological revolution. Nine inches long and weighing two pounds, this phone could only make 30-minute calls and was a workout to cart around. This "block" would later evolve to become the 100-gram thin smartphone that slides easily into back pockets with applications that were never imagined. Cell phones, or rather smartphones, give immediate access to hundreds of options from texting and video chat to checking bank accounts and depositing a check.
One change to the phone that significantly altered the way they are used was the addition of the built-in camera. First added in 2002, the camera phone offered a new, cheap way for people to capture timeless moments. Before the camera phone, every picture taken cost money as film was used and paper was required to print the image. The convergence of the camera and the phone eliminated these costs and provided a more lightweight, efficient way to take photos.
built-in camera began as a free mode for taking a limited amount of poor quality photos, it has evolved to a high definition camera capable of taking thousands of photos and videos. It is predicted that nearly one trillion photos will be taken on phones in 2015 alone. The camera has paved the way for apps like snapchat and instagram where photos can be immediately shared with friends. It allows video chats with family or friends who are halfway around the world giving society yet another way to stay connected.
