"An asterisk ( * ) (Latin asteriscum "little star", from Greek ἀστερίσκος ) is a typographical symbol or glyph. It is so called because it resembles a conventional image of a star." IT is used to highlight and emphasize. This is why we used this symbol in our tree. Marketing is also the discipline to highlight and emphasize your products and services in the marketplace. Thus the connection. Thanks for your consideration!
