Elvis burst on to the list at number 11 and marketing agencies such as Kitcatt Nohr Alexander Shaw, Market Makers and RPM did well too.
Elvis put its success down to its ability to transform people into "screaming, cavorting, knicker-hurling maniacs", a bit like fans of the King himself.
Diary does have to question the judgment on one point, though. On Fridays, Elvis staff compete to wear the wackiest hat. Surely, that sort of team bonding antic should move Elvis down the list?
In advertising, Miles Calcraft Briginshaw Duffy and WAA were new entries at 73 and 45, but Wieden & Kennedy's mantra "Be useful. Be beautiful. Be thought-provoking", is clearly proving a little hard to live up to, with the agency dropping from 31 to 74.
