The global male population was estimated to be 3.5 billion in 2009. http://www.geoh … pop_gender.aspx
I would say that a very large proportion do not have internet access (areas of South America, Africa, India, China, Indonesia, Bangladesh, Afghanistan) or the access they do have is limited (Arab states, China) and the internet is the major resource for this information. Just because we live in an information rich culture does not mean that everyone does.
Global internet usage in 2008 was estimated to be 1.8 billion in 2008 (this will have risen since then). http://www.goog le.com/publicda … internet+access
I just don’t think that 1/3 of men have access to the information, and most don’t have access to the information that lets them know whether they are big or small, so why would they care.
