Interval Research, incubator for consumer internet services founded by Paul Allen & David Liddle

Interval Research Corporation was a private research laboratory based in Palo Alto, California, focused on long-term, blue-sky research in early-stage information technology and consumer innovations. The organization aimed to define future issues, create foundational technologies, and foster new industries through spin-offs or joint ventures rather than immediate product development, primarily funded by Paul Allen's personal investment. Specific financial metrics, employee counts, or user data for Interval Research are not publicly available. Its team included notable figures such as co-founder David Liddle, a veteran of Xerox PARC, alongside researchers like Meg Withgott and Debby Hindus. Initially planned for a decade of operation, the lab shifted focus from pure research to marketable products in late 1999, shortly before its closure around 1999-2000. Interval Research was founded in 1992 by Microsoft co-founder Paul Allen and David Liddle.

High-Level Overview

Interval Research Corporation was a pioneering technology research lab and incubator founded in 1992 by Microsoft co-founder Paul Allen and computer scientist David Liddle, aimed at fostering innovation in consumer technologies like broadband, interaction design, advanced devices, and early internet applications.[1][2][3] Operating from Palo Alto, California, it assembled a multidisciplinary team of over 150 researchers—including hardware designers, programmers, social scientists, artists, and interaction experts—to explore ideas beyond short-term markets, explicitly avoiding the 1-3 year horizons dominating the industry.[1][3] Backed by Allen's $100 million investment, Interval sought to emulate Xerox PARC's creativity but with a sharper focus on commercialization through technology licensing or company spin-offs; it announced its first three spinoffs in 1996 but ultimately closed around 2000 without achieving widespread commercial success.[2][3][4]

Origin Story

Interval Research emerged from Paul Allen's vision to recapture the groundbreaking spirit of Xerox PARC, where David Liddle had been a key figure since joining in 1972.[1][3][4] Liddle led PARC's Systems Science Lab, contributed to the POLOS project, and later drove the development of the Xerox Star—the first GUI-based workstation featuring icons, desktop metaphors, dialog boxes, and Ethernet—which influenced giants like Apple and Microsoft, though Xerox failed to capitalize commercially.[1][2][4] In 1991, Allen recruited Liddle to lead this new venture, launching Interval in 1992 as a secretive lab to "stir up new thinking for commercial possibilities."[1][2][5]

The name "Interval" symbolized the transitional period between old and emerging tech paradigms, with Allen committing funds through 2002 (even printed on name tags).[4] Liddle served as president and CEO until 1999, organizing work around fluid, cross-disciplinary projects rather than silos, drawing top Silicon Valley talent.[1][4] Early efforts spanned consumer devices and internet tech, but by the mid-1990s, amid dot-com pressures, it pivoted from pure research to product development, announcing spinoffs in 1996—its first market tests—before Liddle stepped down in 1999 and the lab shuttered around 2000.[3][4]

Core Differentiators

• Multidisciplinary "All-Star" Team and Project Model: Unlike siloed research labs, Interval mixed computer scientists, designers, behavioral experts, and artists (150+ staff), with researchers fluidly contributing to 2-3 projects simultaneously in an open Palo Alto space to spark serendipitous innovation.[1][3][4]
• Long-Horizon Focus Beyond Short-Term Markets: Rejected 1-3 year product cycles, targeting "seedlings" like broadband consumer devices and interaction design, explicitly looking past immediate internet hype.[3][4]
• Commercialization Intent with PARC Lessons: Modeled after PARC but emphasized spin-offs and licensing (e.g., 1996 trio of startups from Allen's $100M investment) to avoid Xerox's fate of inventing breakthroughs without profiting.[3][4]
• Leadership Pedigree: Liddle's PARC/Xerox Star experience and Allen's Microsoft wealth provided credibility and resources, with Liddle later influencing boards like Santa Fe Institute and NY Times.[1][6]

Role in the Broader Tech Landscape

Interval rode the early 1990s wave of consumer internet and digital interaction optimism, positioning itself as a "1990s PARC" to address industry complaints about desktop-centric stagnation post-PC boom.[3][4] Its timing capitalized on broadband's rise and pre-dot-com hunger for GUI-derived consumer tech, but market forces like accelerating commercialization pressures forced a pivot from exploratory research (e.g., no more music/games) to spin-offs amid skepticism about its secretive outputs.[4] Though it closed without blockbuster hits, Interval influenced the ecosystem by seeding ideas in interaction design and internet devices, validating multidisciplinary incubators, and highlighting tensions between blue-sky research and venture timelines—lessons echoed in modern labs like those from Allen's Vulcan Inc. or AI-focused ventures.[1][2][3]

Quick Take & Future Outlook

Interval's legacy as a bold, if unrealized, bet on patient innovation underscores enduring challenges for research labs in fast-moving tech landscapes. Post-closure, Liddle became a venture capitalist at U.S. Venture Partners, while Allen pursued media and spacetech via Vulcan; no direct revivals exist, but their model informs today's deep-tech incubators amid AI and AR/VR trends.[2][1] Looking ahead, similar "interval" periods—between AI hype and practical consumer apps—could revive Interval-style labs, evolving their influence toward hybrid research-VC models that better bridge invention to scale. This echoes the original hook: a Microsoft co-founder's incubator that dared think decades ahead, planting seeds for tomorrow's PARC equivalents.
