Platform

Common senses and types

• Physical structures: raised floors, stages, railway platforms, offshore oil platforms and construction scaffolds.
• Computing and technology: hardware or software environments (operating systems, cloud services, mobile ecosystems) that run applications and mediate services.
• Business and marketplaces: platform business models that enable interactions between distinct user groups (marketplaces, social networks, gig-economy apps).
• Political and organisational: a set of policies, goals, or promises presented by a party or candidate.
• Other: geological platforms (stable crustal regions), footwear platforms, and figurative uses such as artistic or promotional platforms.

Characteristics vary by type but often include an interface or surface, rules that govern use, and an intended set of participants. For technological and commercial platforms, key features are interoperability, extensibility and the ability to attract and coordinate multiple users or developers.

History and development

The English word derives from French plate-forme (literally "flat form") and originally described physical surfaces. Over time the term broadened into metaphorical use in politics, commerce and technology. In the 20th and 21st centuries, advances in computing and telecommunications popularised the idea of software and digital platforms as environments that host other services and mediate exchanges.

Platforms are important because they lower barriers to participation, enable specialization and create network effects: the value of a platform often grows as more users or providers join. At the same time platforms raise issues of governance, competition and safety—who sets the rules, how disputes are decided, and how risks are managed.

Distinctions to note: a platform differs from a single product in that it supports multiple complementary activities; it differs from a mere marketplace by often providing tools, standards and rules that shape how participants interact. Understanding the type and governance of a platform is crucial when assessing its social, economic and technical impacts.
