THE ESSENCE: Martin Agency keeps producing top-flight TV spots for big brands like UPS and Miller Brewing Co.'s Miller Genuine Draft. The Interpublic-owned shop, based in Richmond, Va., didn't net any big new blockbuster accounts in 2005, but it did win its fair share of new business without losing anything major. Wins included Delta Faucet and Genworth Financial, work for Miller Brewing's Brutal Fruit and Genuine Draft. And that's no mean feat at a time when midsize agencies often find themselves getting squeezed by both global players and hot boutiques. If there was a disappointment, it was its failure to convert on the closely watched BMW pitch.
