From typewriter keys and teletype terminals to mechanical switches, membrane boards, and wireless ergonomic designs—the keyboard shaped how humans talk to computers.
The keyboard descends from 19th-century typewriters. Christopher Latham Sholes helped popularize the QWERTY layout, and teletype machines later bridged typing to early computers. When personal computers arrived, the keyboard became the default text input for command lines, programming, and office work.

Keyboard evolution in one view
Keyboards evolved from heavy mechanical typewriters into compact laptop chiclet keys, enthusiast mechanical switches, and low-profile wireless boards integrated with tablets and smart TVs.
Keyboard evolution: from mechanical typewriters to today’s PC, laptop, and enthusiast boards.
Typing Begins1870s – 1950s
Typewriter and Early Key Layouts
Typewriter era: mechanical keys and QWERTY layouts that still shape modern keyboards.
1873: Sholes & Glidden typewriter spreads QWERTY.
1890s–1920s: Remington and Underwood refine commercial typing.
1930s: Electric typewriters add motor-assisted keystrokes.
Before computers, humans entered text through mechanical typewriters—lever arms struck ink onto paper, and the QWERTY arrangement was designed to reduce jamming on early machines.
Technology Used
Mechanical levers: Each key triggered a metal arm.
QWERTY layout: Letter arrangement still used today.
Ink ribbon: Temporary character impression on paper.
Features
Physical feedback: Audible, tactile keystrokes.
Single function: Document creation, not programming.
Heavy desktop devices: No portability.
Computer Input1950s – 1970s
Teletypes and Computer Terminals
1950s–60s: Teletype machines connect to mainframes.
1970s: Video terminals replace paper teletypes.
Keyboards become the standard operator interface for batch and interactive systems.
Teletypes translated keystrokes into electrical signals sent to mainframes—operators typed commands and received printed or on-screen responses, establishing the keyboard as the primary computer input.
Technology Used
ASCII encoding: Standard character codes.
Serial communication: Characters sent one by one.
Monochrome CRT terminals: Green/amber text displays.
Features
Command-line workflows: Text-first interaction.
Shared terminals: Multi-user lab and datacenter use.
Fixed layouts: Limited ergonomic variation.
PC Standard1980s – 1990s
Personal Computer Keyboard Era
PC keyboard era: standardized desktop layouts, membrane switches, and dedicated ports like PS/2.
1981: IBM PC Model M lineage influences desktop keyboards.
1980s: Function keys and numeric keypads become common.
1990s: Windows and Mac keyboards add modifier and media keys.
The PC boom standardized full-size layouts with function rows, arrow clusters, and numeric pads—membrane switches under plastic keycaps made mass production affordable for homes and schools.
Technology Used
Membrane switches: Rubber dome contact layers.
PS/2 and AT connectors: Dedicated keyboard ports.
Scissor and dome mechanisms: Cost-effective key travel.
Features
104-key layouts: Familiar desktop form factor.
Productivity focus: Spreadsheet and word processing.
Wired reliability: Simple plug-and-type setup.
Portable Typing2000 – 2012
Laptop and Chiclet Keyboard Generation
Ultraportable laptops shrink key travel and width.
Chiclet-style flat keys appear on netbooks and MacBooks.
Backlit keys support low-light mobile work.
Mobility demanded thinner keys and tighter spacing—chiclet caps, short-travel scissor mechanisms, and integrated touchpads turned the keyboard into part of a clamshell portable package.
Cherry MX-style mechanical keyboards resurge with gamers and programmers.
Bluetooth and 2.4 GHz wireless boards cut cable clutter.
Hot-swappable and RGB models grow in enthusiast markets.
Users rediscovered tactile mechanical switches while wireless protocols made clean desks practical—custom layouts, programmable layers, and per-key lighting turned keyboards into personal tools.
Multi-device pairing: One board for PC, tablet, phone.
AI autocomplete: Predictive and generative text aids.
Features
Ergonomic splits: Reduced strain for long sessions.
Hybrid workflows: Voice + keyboard + touch.
Sustainable materials: Recycled plastics and repairable designs.
