"The unique feature of the Market Economy is precisely that it organises economic activity around information" - Peter Drucker. However, a single holistic definition is required because information has different meanings in both the business and technological design disciplines covered (e.g. economics, marketing, engineering, software). The Information Revolution has a common pattern with other historic Technological Revolutions (e.g. steam & railways, oil & automobile) with a common pattern - a techno-economic phase followed by a socio-political one. 'Tech Titan' pioneers (like Facebook, Microsoft, Google) have erupted to become over 20% of today's US stock market capitalisation. However society still needs to address after-effects like data privacy, surveillance and 'harm' from social media. Topics covered include Moore's Law, digital platforms (e.g. Apple), digital markets (e.g. Uber), cloud computing (e.g. Amazon Web Services), 'creative destruction', and how intangible digital products differ economically from conventional physical ones.
