AGU vs. AMS (where "A" stands for American)

AMS:

The AMS, founded in 1919, is the nation's leading professional society for those involved in the atmospheric and related sciences. With more than 11,000 (13,000?) members, the Society promotes the development and dissemination of information on atmospheric, oceanic, and hydrologic sciences through scientific journals, conferences, and public education programs across the country.

AGU:

The American Geophysical Union (AGU) is an international non-profit scientific association with over 60,000 members. Established in 1919 as a committee within the National Research Council of the National Academy of Sciences, AGU was independently incorporated in 1972. Since its founding, AGU is dedicated to furthering the sciences of geophysics through the individual efforts of our members and in cooperation with other national and international scientific organizations. These goals are met through publishing scientific journals and other technical publications, sponsoring scientific meetings of various sizes throughout the year and a variety of other educational and scientific activities.

The AGU has been making lots of progress. One thing I really like is their "Editors’ Highlight."

I saw some pie charts at the AGU site, which show the publication brings in a net 2% (so does the membership).  I don't know how to run a big non-profit organization like the AGU or the AMS, but I suppose 2% is a lot of money (and a lot of work) ...
