PARC History Timeline

1970: PARC Founded

Xerox Corporation assembles a team of world-class experts in information and physical sciences to become what is known as ‘The Architects of Information.’ The company establishes the Xerox Palo Alto Research Center (Xerox PARC) under the direction of Dr. George Pake. The charter for Xerox PARC is to create ‘The Office of the Future.’

1971: Laser printing

Xerox PARC modulates a laser to create a bit-mapped electronic image on a xerographic copier drum. Not only does this demonstrate a novel way to print documents, but this invention of laser printing enables seamless rendering of digital documents onto paper, creating a multibillion dollar printing business for Xerox.

1972: Object-oriented programming

Xerox PARC designs Smalltalk – an object-oriented programming language that enables programs to be improved without being entirely rewritten. This innovation revolutionizes the software industry and influences subsequent programming systems.

1973: Alto PC

The Xerox Alto personal workstation is created. Its client-server architecture means computing is no longer restricted to the hierarchical world of large, centralized mainframes. This evolving PC will subsequently employ the world’s first bit-mapped display, graphical user interface with windows and icons, WYSIWYG (What You See is What You Get) editor, local area network/file storage, and commercial mouse.

1973: Ethernet

An internal memo proposes a system of linking workstations, files, and printers together using a coaxial cable within a local area network. The benefit is that components can join or leave the network without disturbing data traffic. The memo’s author coins the term “Ethernet” to describe the network. Ethernet grows into a global standard.

1973: Superpaint frame buffer

Xerox PARC computer scientists record the first video image on the first computer paint system – a graphics program and framebuffer computer. This paves the way for the earliest computer animations and later earns its inventors an Emmy and an Academy Award.


Xerox PARC coins the phrase to describe cut-and-paste bit-mapped editing: What You See Is What You Get (also known as ‘wizzy-wig’). This year, Xerox PARC also demonstrates the seminal Bravo word processing program (which leads to Microsoft Word) and device-independent imaging (which leads to Page Description Languages and influences subsequent design of Postscript).

1975: Graphical user interface (GUI)

Xerox PARC debuts the first GUI, which uses icons, pop-up menus, and overlapping windows that can be controlled easily using a point-and-click technique. The GUI famously (or infamously) influences the development of all subsequent personal computer interfaces.

1977: VLSI circuit design

Xerox PARC (with Caltech) defines a new representation of Very Large Scale Integration (VLSI) circuit design. This allows for greater computing power in more compact machines, reduces design time, and leads to a new generation of computer-aided design tools.

1979: Corporate ethnography

PARC pioneers the use of ethnography for human-centered technology design, work practice redesign, and more. It requires initiating collaboration among computer scientists, engineers, anthropologists, sociologists, psychologists, and other social scientists. This approach leads to improvements in many workspaces, office products, and processes.

1979: Natural language processing

To enable spell-checking, dictionary, and other tools, Xerox PARC invents computational linguistic technologies based on understanding the structure of language. These lead to computer-automated visual recall, intelligent retrieval, and linguistic compression…and later enable deep meaning-based language parsing systems for search, text analytics, and more.

1980: Optical storage

Non-erasable, magneto-optical storage device technology is developed at Xerox PARC. Initially, its purpose is to enable high-speed data access on the Palo Alto campus. Eventually, it becomes commercialized through Optimem (which evolves into Cipher Data Products).

1980: Programming languages

Xerox files the software copyright for Smalltalk-80. It’s one of only three software copyrights in existence. Meanwhile, Interlisp and Cedar (the successor to Xerox’s Mesa programming environment) are implemented in Xerox systems, enhancing reliability and supporting rapid development.

1982: Fiber optics

The first optical cable-based local area network is operational. Eventually, it will enable commercial, fiber optic media for Ethernet, marketed through Synoptics (later acquired by Bay Networks, then Nortel Networks).

1983: a-Si for printing

A one-inch array of amorphous silicon (a-Si), thin-film transistors is used to drive a small Corjet ionographic printhead. This technology enables Xerox to offer lower cost multifunction machines. Evolving expertise in a-Si thin-film transistors and sensors will become the backbone for many large-area electronic technologies.

1986: Multi-beam lasers

Xerox PARC is home to the world’s first dual-beam lasers. These print twice as fast as single beams. Multi-beam lasers become a key enabler for high-speed, high-resolution production printing systems.

1987: Unicode/multilingual computing

Xerox PARC designs a 16-bit coding system to represent any world script – in documents, user names, file names, or network services – in any combination with a single encoding. These scripts lead to the ISO/IEC 10646 and the corresponding Unicode industry standard that allow computers to consistently represent text.

1988: Ubiquitous computing

The term ‘ubiquitous computing’ is coined at Xerox PARC to describe a future where people seamlessly access resources and control environments using mobile devices. Xerox PARC invents and builds fundamental devices that enables this to happen. Examples include the palm-sized PARCTab, notebook-sized PARCPad, lightweight portable document reader, and flexible computational infrastructure.

1989: Embedded data glyphs

After inventing data glyphs, Xerox PARC pioneers the development of embedded data schemes that transform paper, and other surfaces, into computer-readable interfaces. Applications evolve to include check verification, smart paper, tracking codes, and much more.

1989: Information visualization

Taking a unique approach to the visualization of information, Xerox PARC invents techniques that use human perceptual and cognitive capacities to help people make sense of large amounts of diverse information. The approach results in 3D rooms, the hyperbolic browser, and other ‘Focus+Context’ visualization techniques that present 3D views of information databases.

1990: a-Si displays and digital x-ray imaging

Xerox PARC builds the first x-ray imager using amorphous silicon. Continuing research will result in the formation of the company dpiX, which will market the world’s highest resolution active matrix, liquid crystal, flat-panel display and a digital x-ray system for medical imaging – thereby eliminating the reliance on traditional film.

1990: Multi-user virtual world

Xerox PARC creates LamdaMOO, one of the oldest continuously operating real-time multi-user ‘dungeons’ or online environments. LamdaMOO provides a foundation for the U.S. Department of Defense’s collaborative computing systems, and later results in a company that provides live, web-based meeting and presentation solutions (and ultimately becomes Microsoft Live Meeting).

1992: Collaborative filtering

Collaborative filtering is implemented at Xerox PARC, inspired by the idea to involve human input (such as past user preferences and collaborators’ feedback) in helping information systems auto-filter content. Today, this approach enables recommender systems.

1992: Internet standards

The MBone Multicast backbone is co-founded and first implemented at Xerox PARC to deliver real-time multimedia over the Internet. Xerox PARC scientists will also play a key role in co-designing the IPv6 protocols that govern and define how the Internet works, as well as help develop the HTTP-NG protocol based on Inter-language Unification (ILU) from Xerox PARC.

1997: Blue laser

Xerox becomes the first printing company to create a blue laser. The reduced wavelength of a blue laser ultimately allows much higher resolution printing than is possible with the standard red and infrared lasers.

2000: Electronic reusable paper

A thin, flexible and portable document display technology invented at Xerox PARC. It looks and feels like paper; however, it can display different text and graphics when an electric charge is applied to it.

2000 Digital Rights Management (DRM)

Xerox PARC’s concepts for trusted systems and digital property rights lead to the joint venture called ContentGuard. This DRM software offers content owners greater control and flexibility over the distribution of their material. To enable authorization of content access in a universal language, Xerox PARC develops eXtensible rights Markup Language (XrML).

2001: Biomedical systems

Xerox PARC partners with The Scripps Research Institute to develop instrumentation and information systems for accelerating discovery in the life sciences. In 2002, PARC demonstrates an operational prototype of the Fiber Array Scanning Technology Cytometer for screening blood samples about 1,000 times faster than automated digital microscopy.

2002: PARC established

To broaden PARC’s ability to innovate, build breakthrough technology platforms, and develop business concepts for many different organizations, PARC is established as an independent company.

2007: Powerset deal

PARC and language search company Powerset sign an exclusive deal to commercialize breakthrough technology in consumer search. After three decades of research, PARC’s natural language technology becomes ready to work with.

2010: PARC spins out PowerCloud systems

Walden Venture Capital and Javelin Venture Partners join with PARC to spin-out PowerCloud Systems, focused on offering cloud-managed networking solutions for small and medium-sized businesses.

2010: Thinfilm works with PARC

Advanced printed memory provider, Thinfilm, partners with PARC to develop next-generation printed memory solutions. Together, we use low-cost printed electronics to enable high-capacity and compact form-factor memory.

2013: PARC expands Japan presence

PARC announces its new office in Tokyo, expanding its presence in Japan. The new Tokyo-based team works with clients including Hitachi, Panasonic Corporation, Honda and Sony, among others.

2016: PARC and East Japan Railway Company

JR East chooses to work with PARC on the development and deployment of a new condition-based maintenance solution. PARC’s hybrid approach is proven to be a more effective way to maintain railways than a schedule-based approach.

2017: PARC spins off Metawave

PARC reveals its intention to spin off wireless technology startup, Metawave, which builds technology solutions based on engineered metamaterials and Artificial Intelligence (AI) to commercialize smart beamsteering antenna systems for autonomous vehicles and 5G markets.
