In these crisscrossing threads are woven the fabric of a community, a society, an economy, a nation. And beyond that, the world itself. But the technology isn't the dream. The dream is what you can do with it.' Three revolutions changed the face of South Africa, the economic powerhouse of the African continent, in 1994. The first was democracy, as millions of newly-enfranchised citizens went to the polls to elect a new government. The second was the internet, bringing information, learning and entertainment into millions of homes. But the real signal of change in the air was the arrival of an electronic device that would put undreamed-of power into the hands of the people. The cellular phone. In a country where less than four per cent of the population had access to a landline phone, mobile telephony opened the gateway to new ways and new worlds of communication. Today, more than 90 per cent of South Africans own at least one mobile phone, and they're not just using them to talk to each other. Mobiles have become tools of education, entrepreneurship, trade, empowerment, activism, media and upliftment. With the advent of the mobile internet, mobiles have also become the hubs of the most powerful force in modern communication. The social network, bringing people together in an interchange of ideas, opinions, chatter and commerce that is changing the way we understand and define communities. This is the story of the biggest and fastest-growing social network in Africa. A network that took shape in the townships of the Western Cape and has grown to be part of the lives of more than 50 million users in 120 countries, sending more than 23 billion messages a month. This is the story of Mxit. A cultural force, a community of millions, with its own economy, its own infrastructure, its own language and its own traditions. This is the story of Mobinomics, the new economy of mobile, and how it is connecting people and changing lives. Read it and learn. Read it and understand. Read it and be moved by the power of mobile.

The dark truth is that it has become very hard to find anyone (and certainly anything) more interesting than one's smartphone. This perplexing and troubling realisation has for most of us had huge consequences for our love stories, family lives, work, leisure time and health. This is why we have created Phone Detox, a palm-sized book filled with insights, ideas and meditations about the complex relationship we have with our phones. Phone Detox knows we love our phones and would never want us to give them up, but it is also gently aware that these delightful gadgets bear a hidden cost. This flip book is a tool that aims to bring a little sanity to our closest, most intense and possibly most danger-laden technological relationship. What people are saying about Phone Detox: "Must read. Very enlightening." Robert "I got it as a birthday present for my husband; and it is currently doing rounds among our friends, as we all found its little snippets of psychologically philosophic wisdom inspiring and very useful."

The #1 New York Times bestselling author of Grain Brain and his physician son explore how modern culture threatens to rewire our brains and damage our health, offering a practical plan for healing. Contemporary life provides us with infinite opportunities, along with endless temptations. We can eat whatever we want, whenever we want. We can immerse ourselves in the vast, enticing world of digital media. We can buy goods and services with the touch of a button or the swipe of a finger. But living in this 24/7 hyper-reality poses serious risks to our physical and mental states, our connections to others and even to the world at large. Brain Wash builds from a simple premise: Our brains are being gravely manipulated, resulting in behaviours that leave us more lonely, anxious, depressed, distrustful, illness-prone and overweight than ever before. Based on the latest science, the book identifies the mental hijacking that undermines each and every one of us and presents the tools necessary to think more clearly, make better decisions, strengthen bonds with others and develop healthier habits. Featuring a 10-day boot camp program, including a meal plan and 40 delicious recipes, Brain Wash is the key to cultivating a more purposeful and fulfilling life. 'By showing us how to consciously rewire our brains for connection, compassion, and better decisions, Brain Wash provides a framework for reclaiming joy and health in the modern world.' - Deepak Chopra, author of Metahuman 'Brain Wash reveals how our day-to-day decisions are deeply influenced and actively manipulated by the modern world. But more importantly, it is a powerful manual that allows each of us to reclaim control of our choices and make better decisions that will pave the way for health and happiness. While we generally know what's best for ourselves, acting on this knowledge is a constant struggle. Brain Wash allows us to turn this knowledge into action. I highly recommend this innovative book.' - Daniel G. Amen, MD, founder, Amen Clinics and author of The End of Mental Illness
