In the older Periodic Table, each group was divided into A & B sub-groups. The only problem with that was that there were two different conventions about which elements were labelled "A" and which were labelled "B". Groups 1 & 2 were clearly 'A' (elements like sodium and calcium) and 11 & 12 were clearly 'B' (elements like copper and zinc). But groups 3 through 10 were labelled 'A' in one convention and 'B' in another, and the opposite labels were used for groups 13 through 18.
With the second labelling convention, groups labelled 'A' were known as 'main group elements', and groups labelled 'B' were 'transition metals', and that is still the case.
Thus in the newer IUPAC scheme, groups 1, 2, and 13 through 18 are called 'main group elements'.
