As part of the promotion for his new Modern Times album, Bob Dylan's decision to appear in an iTunes ad has opened the artist up to new audiences, a report claims.

The Apple ad exposed the reclusive US artist to a younger age group, helping propel his sales to "places they hadn't been since the Ford administration," according to Advertising Age.

Brad Fay, chief operating officer of the Keller Fay Group says: "Apple is part of a new series of iconic brands that are themselves celebrities. These brands have become a conversation currency, a social currency, a natural part of human interactions."

Consumers are also battle-hardened now, over-exposed to advertising they look for propaganda that "brings higher levels of value and meaning", the report explains.
