Diageo is working on new ads which will replace its Good Things Come to Those Who Wait' campaign for Guinness. It has instructed its agencies Saatchi and Saatchi and Abbot Mead Vickers BBDO to work on new creatives. A Guinness UDV spokeswoman said nothing had been finalised although the brewer began filming an ad this week in Ireland which it plans to use in the UK and other Guinness Draught markets. {{DRINKS }}
