Offering a deeper understanding of today's internet media and the management theory behind it Platforms are everywhere. From social media to chat, streaming, credit cards, and even bookstores, it seems like almost everything can be described as a platform. In The Platform Economy, Marc Steinberg argues that the "platformization" of capitalism has transformed everything, and it is imperative that we have a historically precise, robust understanding of this widespread concept. Taking Japan as the key site for global platformization, Steinberg delves into that nation's unique technological and managerial trajectory, in the process systematically examining every facet of the elusive word platform. Among the untold stories revealed here is that of the 1999 iPhone precursor, the i-mode: the world's first widespread mobile internet platform, which became a blueprint for Apple and Google's later dominance of the mobile market. Steinberg also charts the rise of social gaming giants GREE and Mobage, chat tools KakaoTalk, WeChat, and LINE, and video streaming site Niconico Video, as well as the development of platform theory in Japan, as part of a wider transformation of managerial theory to account for platforms as mediators of cultural life. Analyzing platforms' immense impact on contemporary media such as video streaming, music, and gaming, The Platform Economy fills in neglected parts of the platform story. In narrating the rise and fall of Japanese platforms, and the enduring legacy of Japanese platform theory, this book sheds light on contemporary tech titans like Facebook, Google, Apple, and Netflix, and their platform-mediated transformation of contemporary life-it is essential reading for anyone wanting to understand what capitalism is today and where it is headed.

We live in a world where social interaction is increasingly mediated by technological devices. In this book, Ian Hutchby explores the impact these technologies have on our attempts to communicate. Focusing on four examples - telephones, computerized expert systems at work, speech-based systems dealing with enquiries from the public, and multi-user spaces on the Internet - Hutchby asks: are we increasingly technologized conversationalists, or is technology increasingly conversationalized?
Mobile telephony has arrived on the scene.According to statistics of the International Telecommunications Union, in the mid-1990s, less than one person in 20 had a mobile telephone; as of 2003, this had risen to on p- son in five.In the mid-1990s, the GSM system was just being commerci- ized, there were serious coverage and interoperability issues that were not yet sorted out and handsets were only beginning to be something that did not require a car to transport them.In the mid-1990s, if a teen owned a mobile telephone it was likely an indicator of an over-pampered rich kid rather than today's sense that it is a more or less essential part of a teen's everyday identity kit. Hence, in less than a decade, this device has established itself tech- cally, commercially, socially and in the imagination of the people.It has changed the way we think about communication, coordination and safety and it has changed the way we behave in the public sphere. The mobile telephone has become an element in our sense of public and private space and in the development of our social and psychological personas.It has become an arena wherein the language is being played with, morphed and extended.Finally, it is reaching out into ever-new areas of commerce and interaction. All of this is, of course, interesting to social scientists.As brought out by Woolgar later, this is, in some ways, a type of experiment writ large that has engendered serious insight into the functioning of the social group and the individual in soc
