Digital technologies are fast becoming indispensable. A growing array of devices and technologies are on offer today, making users much more mobile. While it took around 21 years to reach the first billion mobile users, the second billion signed up in just three years. Therefore, it is not surprising that in today's world, digital business becomes big business.The clearest evidence for this is at the macro-economic level, where the contribution of ICTs to the general economy has grown rapidly, regardless of falling prices. Mobile, broadband, user-generated content and IPTV are some of the technologies highlighted as the underlying enablers of new lifestyles. The report, part of a series written yearly by ITU, explores the changing nature and role of the digital individual and of digital identity with examples and scenarios. The "digital-life" report shows human lives increasingly entwined with technology enabling virtual identities to be constructed and digital personae to exist with recreational commercial and sometimes malicious purpose.
