The first smartphone was Nokia 9210, launched as early as 2001. It was followed by Nokia Series 60, Sony Ericsson P800, and the smartphones of Motorola and Siemens. Smartphones quickly became popular while sales dropped for PDAs. In February 2005, Sony stopped selling PDAs. Smartphones represented 3,7% of all cellphones sold in 2004, and 9% in 2006, with 90 million smartphones sold for one billion cellphones. January 2003 > The Public Library of Science, a publisher of free high- quality online journals In early 2003, the Public Library of Science (PloS) -- founded in October 2000 - created a non-profit scientific and medical publishing venture to provide scientists and physicians with free high-quality, high-profile online journals in which to publish their work. The journals were PloS Biology (launched in 2003), PLoS Medicine (2004), PLoS Genetics (2005), PLoS Computational Biology (2005), PLoS Pathogens (2005), PLoS Clinical Trials (2006), and PLoS Neglected Tropical Diseases (2007), the first scientific journal on this topic. All PloS articles are freely available online, on the websites of PLoS and of PubMed Central, the public archive run by the National Library of Medicine (United States). The articles can be freely redistributed and reused under a Creative Commons license, including for translations, as long as the author(s) and source are cited. February 2003 > A quote by Nicolas Pewny, consultant in electronic publishing A bookseller, publisher -- he founded the small publishing house Le Choucas in 1992 -, and consultant in electronic publishing, Nicolas Pewny wrote in February 2003: "I see the future digital book as a 'total work' putting together text, sound, images, video, and interactivity: a new way to design, and write, and read, perhaps on a single book, constantly renewed, which would contain everything we have read, a single and multiple companion. Utopian? Improbable? Maybe not that much!" (NEF Interview) February 2003 > Handicapzero, a portal for visually impaired users In February 2003, the association Handicapzero launched a general portal for visually impaired French-speaking internet users, offering free access to national and international news, sports news, TV programs, the weather forecast, and access to a full range of services for health, employment, consumer goods, leisure time, sports, and telephony. Handicapzero -- founded in 1987 - has aimed to improve the autonomy of visually impaired people in the French-speaking world, that is to say around 10% of the population. Launched in September 2000, the first website of the association quickly became the most visited "adapted" website in the French-speaking community, with 10,000 queries per month. Since October 2006, a revamped portal (based on the one launched in February 2003) has offered more tools for blind people, for visually impaired people, and for people who want to communicate with them. The portal was used by 2 million people in 2006.
