Ten years later, in June 2011, Henk explained: “I have always followed the development of ebooks with much interest, as a professor in communication systems and an organizer of study tours in Silicon Valley. I didn’t use them much during 40 years, because of the lack of progress in reading devices. I never liked reading a book on a computer or PDA. Now, with tablets like the Kindle of the iPad, I am finally reading ebooks. I see a huge expansion of digital reading with tablets that are easy to use and with a very large choice of ebooks thanks to electronic commerce and companies like Amazon.” What has he been working on lately? “I am a serial entrepreneur who is creating a start-up in the field of mobility. I use the internet all the time to find partners and ideas. We also use online books to learn the art of innovation!” 2001 > WIKIPEDIA, A COLLABORATIVE ENCYCLOPEDIA [Summary] Wikipedia was launched in January 2001 by Jimmy Wales and Larry Sanger (Larry resigned later on) as a global free collaborative online encyclopedia, financed by donations, with no advertising.
