context_page_description: The third platform is a term coined by marketing firm International Data Corporation for a model of a computing platform. It was promoted as inter-dependencies between mobile computing, social media, cloud computing, and information / analytics, and possibly the Internet of Things. The term was in use in 2013, and possibly earlier. Gartner claimed that these interdependent trends were "transforming the way people and businesses relate to technology" and have since provided a number of reports on the topic.
