For several years, the digital transformation has been taking place in French and international companies. Today, seen by public authorities as a source of growth and competitiveness, digitalisation is taking root in civil and economic society (citizens, consumers, public administrations, private companies).The specialists confirm a real and exponential deployment among individuals, but are committed to seeing the development of digital technologies in still fragile companies. The main reasons for this fear are organizational difficulties, lack of digital knowledge and lack of leadership involvement. However, these same experts confirm the development potential of the French economy, which could result in an increase in the share of the digital sector in GDP by EUR 100 billion per year. The impact of disruptive digital technologies (Cloud Computing, 3D printing, Big Data...) would amount to EUR 1,000 billion in France by 2025.(1)With the end of an unprecedented economic crisis, an unstable economic environment and a high unemployment rate, the digital transition seems to be a potential for rebalancing. All actors in society (public authorities, businesses, education systems, individuals) are involved in participating and contributing to this change. Thus the first users are the individuals: smartphones, laptops, tablets and connected objects are daily dul tools, essential for the vast majority. The latter exploded the scores: one billion searches per day on Google! These technological innovations are changing lifestyles and consumption.
