Example Input: Question: How many teams were a part of the league that ran from 2001-2003 and featured many World Cup stars? Passage:The first women's professional soccer league in the U.S. formed after the success of the 1999 Women's World Cup. The Women's United Soccer Association (WUSA) ran from 20012003 and featured many of the World Cup stars, including Mia Hamm, Michelle Akers and Brandi Chastain. Its successor Women's Professional Soccer (WPS) ran from 20092012. Currently, the National Women's Soccer League (NWSL) is the top professional league in the country and was formed in 2012. The NWSL season runs from spring to early fall (typically April October). In 2017, A&E Networks bought an equity stake in the league and broadcasts a game of the week on Lifetime, and formerly streamed all games online via the go90 platform. During the 2018 season, the NWSL moved some of the games originally scheduled to air on Lifetime to evening slots on ESPNews (both channels being part of the Disney family), and when go90 owner Verizon shut down that platform at the end of July, the NWSL streamed the games that were intended for go90 on its own website.
