Las Vegas, according to Dana Carvey, is a place for “strippers, hookers and crack”, but this week is full of people who will “stay in their rooms and play Halo” during the Consumer Electronics Show, which is warming up for an official start on Thursday.

Mr Carvey, the onetime star of Wayne’s World and Saturday Night Live, was the “entertainment” at the “CES Unveiled” press preview in the opulent surroundings of The Venetian.
