The file
A phone number you can sing. The Empire man, a copywriter named Lynn Hauldren, wrote the jingle and ended up in the commercials himself for a quarter century, in a suit, promising next-day installation.
Anyone who grew up in a market where Empire advertised can still dial the number, and the company kept it in every city by acquiring the digits. Hauldren died in 2011; an animated version of him carries on.
