content and consumption
This page presents figures on film, book, newspaper and
other content production, supplementing the Communications
Revolution profile
and the Metrics & Statistics guide.
It covers -
base data
Estimates of the amount of content produced and consumed,
particularly prior to the 1960s, are contentious.
A useful overview of global estimates of non-internet
content production and storage (eg of 22,643 newspaper
titles, 40,000 scholarly journals, 80,000 mass-market
periodicals and 40,000 newsletters in 1999) see the 2003
How Much Information report
by Hal Varian & Peter Lyman and UNESCO studies discussed
elsewhere on this site.
internet content
The size & shape page
of our metrics guide points to various internet statistics,
from which we've extracted:
number of registered domains (June 00) - 17.75 million,
100% growth pa
number of pages (00) - between 880 million and 2.4 billion,
depending on the statistical source
time to register first million domain names - four years.
Time to move from 4 to 5 million names - three months
books
Raj Reddy of CMU and the Million Books Project estimates
that 100 million titles have been published globally since
the birth of printing (OCLC's WorldCat covers around 48
million titles), with perhaps 80% dating from after 1900.
Lyman & Varian suggest that the number of new
titles published in US in 1996 was 68,000. In 2004 RR
Bowker, responsible for the Books in Print database,
reported that some 175,000 new titles were published in
the US during 2003. Supposedly some 195,000 new titles
were published in the US during 2004, including 25,184
fiction titles. Over 4,000 new titles were published in
Israel in 2004, compared with some 25,000 in France (with
population 10 times as large).
The overall number of titles in US tertiary education
libraries in 1998 was estimated by the National Center
for Education Statistics as 495.7 million.
newspapers and journals
The reported number of journals published in the US in
1998 was 12,000. The global number of newspaper titles
in 2000 was 8,391 dailies. In the US during 2002 there
were some 6,700 weekly titles, 777 morning dailies and
692 evening dailies. The World Association of Newspapers
(WAN) estimates daily global circulation of newspapers
in 2001 at around 436.2 million copies, of which the EU
accounted for some 78 million copies and Japan for 71
million.
Weekly and monthly magazine titles are reported to amount
to 73,000.
The estimated volume of paper for books, magazines, newspapers
in 2000 was estimated as 130 million tons pa.
Questioning the myth of the paperless office, Kurzweil
comments that US business consumed 850 billion pages of
paper in 1981, 2.5 trillion pages in 1986 and 4 trillion
in 1990. An independent industry study suggested that
the US market for ink cartridges reached US$34 billion
in 2003-4.
film
Drawing on Alan Goble's International Film Index 1895-1990
(London: Bowker 1991) Lyman & Varian suggest that
the global total of moving pictures made from 1890 to
2002 was approximately 368,530, of which 226,771 were
features, 57,825 were shorts and 34,540 were made for
television, 30,475 were documentaries, 113,992 were Black
& White and 49,417 were Silents. An estimated 40,000
were no longer extant. The leading production countries
in 2001 were the US (some 1,740 titles of a global total
of 5,717) and India (1.013 titles).

still images
Around the world, more than 2,700 photographs are taken
every second, with holiday snaps accounting for 80%.
Lyman & Varian (2003) suggest that worldwide around
75 billion film prints were made in 2002, with around
15% wastage of negatives. The total digital storage capacity
of the film rolls produced in 2002 was about 440 petabytes
(87.9 billion photos at 5 MB apiece), with 2.1 billion
photographs being printed from digital cameras. The US
market accounted for around a third of the three billion
rolls of film produced in that year.
Lyman & Varian suggest that approximately 750 billion
photographs existed worldwide in 1999, with addition 150
billion in the following two years. Assuming some 'attrition',
the number of photos in existence at the end of 2003 might
be around 900 billion. Most of those images are not seen
by more than two people. Kodak has reportedly claimed
that only some 2% of photographs are copied or modified
in any way after they are originally developed. The largest
image libraries - Getty
Images (with 70 million images) and Corbis
(with 65 million images) - appear to have digitised under
2% of their collections; most reproductions involve under
1% of those collections. The global market for stock photography
as of 2000 was estimated as being upwards of US$2 billion
pa, with around 40% of revenue going to the two major
libraries.
Figures for the total number of cameras in existence and
use are contentious. It is likely that digital cameras
amounted for around half the cameras in early 2000 (55
million) and now represent over 50% of all photographic
devices if mobile phones with a digital camera feature
(over 25% of an estimated 150 million mobiles sold in
2004) are included in the count.
