As P&G continues to try to regain its mojo after years of subpar performance, Tastad is on the hot seat. New CEO David Taylor is reemphasizing North America, P&G’s largest geographic unit, with $28.7 billion in revenues. But that business will soon be smaller because the company is selling off some 100 brands. The biggest chunk of those, including Wella and Clairol, will move to Coty later this year. Now the Canadian-born Tastad must gin up excitement for such new products as Tide Purclean and Downy Unstopables.
