J.R. Hartley ("Fly Fishing")

Why it works

An elderly man trudges from bookshop to bookshop seeking a copy of "Fly Fishing by J.R. Hartley," fails, and comes home defeated — until his daughter hands him the Yellow Pages. A shop has it. He gives his name: "J.R. Hartley." David Abbott's 1983 twist-ending spot repositioned a directory associated with blocked drains as something for "the nice things in life," lifting non-emergency enquiries from 6% to 20%. The fictional author became so real to the public that a ghost-written Fly Fishing by J.R. Hartley was published in 1991 and became a Christmas bestseller — an ad generating a real product, decades before 'transmedia' had a name. It is studied as perhaps the purest example of warmth and narrative surprise changing the perceived purpose of a utility brand.
