The Wiggles' popularity in the US increased "in the shell-shocked weeks after the terrorist attacks on New York City in 2001", when the group performed there, even when other acts cancelled their tours, a decision that earned them loyalty and respect. According to Cook, the press proclaimed that they were braver than many Australian sports teams that had cancelled their appearances. Paul Field stated, "New York has really embraced them. It was a kind of watershed." Strong sales of the Wiggles videos eventually caught the attention of the Disney Channel in the US, who was impressed by their "strong pro-social message". In January 2002, Disney began showing Wiggles video clips between their programs. By June of that year, the popularity of the clips prompted the Disney Channel to add both seasons of "The Wiggles" series to their schedule and showed full episodes multiple times per day. Field reported that despite their "modest production values", the shows were popular with pre-schoolers.
