The Wiggles used many of the same promotion techniques in the US that they had used in Australia, and chose to keep their concerts simple and maintain the same values that were successful in Australia. The Wiggles performed during the intermission of "Barney Live" stage shows, which "The New York Times" likened to "getting the warm-up slot for the Stones" in the pre-school entertainment world. In 2000, when video sales took off in the US, Lyrick began to distribute Wiggles videos and advertised them by including Wiggles shorts as trailers in their "Barney" videos, which, as Anthony Field stated, "pushed us over the edge". At first, the group's videos were distributed in boutique stores such as FAO Schwarz and Zany Brainy, and on-line. According to Paul Field, they entered the mass media market when their videos became top-sellers at Amazon.com, and their first two videos, "Yummy Yummy" and "Wiggle Time", landed in the top ten at Amazon.com. Stores such as Wal-Mart began to take notice, and began to sell Wiggles videos. The band released nine DVDs in the next three years to keep up with the demand.
