There was a need to transform the fireworks display in a show of the same quality. The fireworks display was created by entrepreneurs Ricardo Amaral and Marius. From the previous 8–10 minutes the time was extended to 20 minutes and the quality and diversity of the fireworks was improved. A technical problem in fireworks 2000 required the use of ferries from New Year's Eve 2001-02. New Year's Eve has begun to compete with the Carnival, and since 1992 it has been a tourist attraction in its own right.
