Actual years of activity were mid-1939 to early 1942 (mostly as Fox Publications, inc.) and mid-1944 to 1951 (mostly as Fox Feature Syndicate, Inc.), with "Blue Beetle" being published by Holyoke Publishing Co., Inc. in the interim. 1944 and to a lesser extent 1945 saw a great deal of activity through surrogate publishers, mostly in the form of giant-size (128 or 196 page) issues alongside the return of an actual Fox publishing company.
