In the last decade (or longer) the preposition around has come to serve in media language as an all-purpose word instead of words and phrases such as “with regard to,“ “concerning,” and “regarding.” The object of around  can be any word or phrase, which makes this preposition ubiquitous. Why it has taken English so long in its history to elevate around to all-purpose utility is just one of those ever-lurking mysteries of language use.
