As early as the 1870s keyboard-like instruments were used for conveying information about the Stock Market across telegraph lines. However, as telegraphs became outdated and new technology was invented, more people like Charles and Howard Krum, Frank Pearne, Royal House, and Frederick Creed began to improve and change the keyboard. By the 1930s typewriters came into play. In the 20th century, ENIAC and BINAC computers (ancestors of our modern-day PCs) were invented and keyboard-like devices were incorporated. In 1967 the old computers evolved into more modern and recognizable computers like the Datapoint 3330, which took use of the keyboard. Nowadays, we have smartphones and touch-screens that allow us to use computers without tangible keyboards.
