Skyr isn't carried in too many American stores, but the Icelandic yogurt definitely has its fans. It is thicker than conventional yogurt, largely because it is strained, much like Greek yogurt. You are most likely to be familiar with the yogurt if it is carried at your local Whole Foods, where it is packaged into small containers and flavored like conventional yogurts, with berries, vanilla, etc. Despite the generally positive reaction from consumers, Whole Foods no longer promotes the fact that they carry Skyr, or any other Icelandic products, because of the company's offical policy of dissapproval for Iceland resuming commercial whaling last year.
The average consumer, perhaps the average Skyr fan, in the US isn't aware of the whaling issue and because Whole Foods hasn't promoted it, they're not likely to - especially because Whole Foods is planning to stock more Icelandic products this spring. Whole Foods will be carrying Nói Síríus chocolate easter eggs in approximately 70 stores. To entice WF to stock the eggs, Nói Síríus seems to have offered them at almost no cost, as the marketing director of the chocolate company said "There are no profits involved, this is first and foremost a sales experiment." More will be imported next year if they prove popular. Whether Whole Foods will be promoting them now, or in future, is still unknown, though it certainly seems like it would be a good business strategy to promote the products you carry if you're going to carry them at all.
