Great agencies (e.g., Wongdoody. Butler Shine, Stern & Partners. Sedgwick Road. Element 79. Creature. Venables, Bell & Partners. Two by Four. Saatchi & Saatchi. Brighthouse. Toy. St. Lukes. Anomaly. Team One.Brew. Rethink. Droga5. Downtown Partners. Martin. Vitro/Robertson. Zig. Hill Holiday. Wieden+Kennedy. Shine.) are all very different.
But bad advertising is all the same.
