Google is the technology company whose culture is associated with “20% time” for personal projects. The policy encouraged engineers to devote roughly one-fifth of their paid work time to ideas they believed could benefit Google, rather than working only on assigned projects.
Google’s version was influenced by 3M’s innovation program and became widely known as the “20% Project” or “Innovation Time Off.” The goal was to give employees room to experiment, pursue interests, and discover products that formal planning might overlook. The arrangement helped make employee-driven innovation a defining part of Google’s public image.
Several well-known Google products are commonly linked to this system, including AdSense and Google News. Gmail is often described as a 20% project, but its creator, Paul Buchheit, has disputed that characterization. The policy has also changed over time: reports in the 2010s questioned how freely employees could use it, while Google later said the principle remained part of its culture.
The common mix-up is treating “20% time” as an invention unique to Google. Other companies, including 3M and Atlassian, have used similar arrangements, but Google popularized the phrase in the technology industry.
