For dive training I have two suggestions: Group the agencies in three areas by their membership (or not) in the standards groups; In the U.S. in 1985 a collaboration was created to standardized dive training and set minimums. This group goes by the name or the Rcreational SCUBA Training Council (RSTC). Members include (alphabetically).... I believe members include NAUI, PADI, SSI, YMCA and others. Can get a list. In Europe the group is CMAS. Members are... Other agencies for dive instruction are...

This could cut down on the advertising/listing.

I think the history section should include, "The first certification for sport scuba diving was in 1959 by the YMCA. The trade association NAUI soon followed with its own course."
