With the advent of the typewriter in the 19th century, symbols began to be standardized, allowing for more consistent communication in written form.

The introduction of the computer keyboard further revolutionized the use of symbols. ASCII (American Standard Code for Information Interchange) was developed in the 1960s to standardize characters, including symbols, for electronic communication. This set the stage for the modern keyboard layout we are familiar with today.

From typewriters to digital devices, the journey of keyboard symbols reflects broader technological advancements. Each symbol, from the simple comma to the complex hash (#), has adapted to meet the changing needs of communication over time.
