The Diverse and Exploding Digital Universe. An updated forecast of worldwide information growth through 2011 (Note:
PDF)
From the EMC Corporation websiteThis white paper calibrates the size (bigger) and growth (faster) of the digital universe. It also seeks to understand the implications for business, government, and society.
Some key findings are as follows:
• The digital universe in 2007 — at 2.25 x 1021 bits (281
exabytes or 281 billion gigabytes) — was 10% bigger than we thought. The resizing comes as a result of faster growth in cameras, digital TV shipments, and better understanding of information replication
• By 2011, the digital universe will be 10 times the size it was in 2006
• As forecast, the amount of information created, captured, or replicated exceeded available storage for the first time in 2007. Not all information created and transmitted gets stored, but by 2011, almost half of the digital universe will not have a permanent home
• Fast-growing corners of the digital universe include those related to digital TV, surveillance cameras, Internet access in emerging countries, sensor-based applications, data-centers supporting “cloud computing,” and social networks
• The diversity of the digital universe can be seen in the variability of file sizes, from 6 gigabyte movies on DVD to 128-bit signals from
RFID tags. Because of the growth of
VoIP, sensors, and
RFID, the number of electronic information “containers” — files, images, packets, tag contents — is growing 50% faster than the number of gigabytes. The information created in 2011 will be contained in more than 20 quadrillion — 20 million billion — of such containers, a tremendous management challenge for both businesses and consumers
• Of that portion of the digital universe created by individuals, less than half can be accounted for by user activities — pictures taken, phone calls made, emails sent — while the rest constitutes a digital “shadow” — surveillance photos, Web search histories, financial transaction journals, mailing lists, and so on
• The enterprise share of the digital universe is widely skewed by industry, having little relationship to GDP or IT spending. The finance industry, for instance, accounts for almost 20% of worldwide IT spending but only 6% of the digital universe. Meanwhile, media, entertainment, and communications industries will account for 10 times their share of the digital universe in 2011 as their share of worldwide gross economic output
• The picture related to the source and governance of digital information remains intact: Approximately 70% of the digital universe is created by individuals, but enterprises are responsible for the security, privacy, reliability, and compliance of 85%
Building a creative innovation economy: opportunities for the Australian and New Zealand creative sectors in the digital environment (Note:
PDF)
From the Cultural Ministers Council websiteThis report provides a high-level discussion of the issues, opportunities, potential future directions and key shared priorities for the Australian and New Zealand creative sectors in the online, mobile and broadcast digital environment. It documents achievements to date and aims to raise awareness about potential future directions for the creative sector in the digital environment.
InterConnections: A National Study of Users and Potential Users of Online InformationFrom the Institute of Museum and Library Services websiteMuseums and libraries have long been sources of learning, recreation and information for personal, family, educational and workplace purposes. However, the Internet, Web and other technologies have become an increasingly used source of information that some believe will largely replace their physical counterparts. On the other hand, some have speculated that the Internet and related technologies and services will actually enhance and increase museum and library use.
Until now, there has been no solid evidence to support either assertion particularly considering the wide range in types of museums and libraries. The “
IMLS National Study on the Use of Libraries, Museums and the Internet,” delves into the use of libraries, museums and the Internet and concludes that “the amount of use of the Internet is positively correlated with the number of in-person visits to museums and has a positive effect on in-person visits to public libraries.”
How digitisation can bring a nation's heritage to the desktops of all (Note: Podcast)
From the Joint Information Systems Committee (JISC) websiteOne of the projects in
JISC's digitisation programme, the Welsh Journals project is set to add to a growing body of materials dedicated to Welsh, culture, history and language. In this podcast, director of the project,
Arwel Jones talks about how digitisation can promote wider efforts to make a nation's culture and heritage available to all.
