I don't know if anyone has noticed this yet but the Jan. 2012 g is now up on jw.org. The average printing per issue is now
41.042,000 which is an increase per issue of 1,129,000 more compared with last year. It is a 2.8% increase. Next thursday the Jan. 1, 2012 w should be up so it should give the updated monthly printing for the w . I'm sure it went up by a similar amount.
Thus over 1 billion magazines were printed by the society during the 2011 SY for any who would be interested in knowing this (aside from me!)
