At the end of 2003, Kasem announced he would leave "AT40" once his contract expired and would be replaced by Ryan Seacrest. He agreed to a new contract to continue hosting his weekly adult contemporary countdown shows in the interim, which at the time were both titled "American Top 20". In 2005 Kasem renewed his deal with Premiere Radio Networks to continue hosting his shows, one of which had been reduced to ten songs and was retitled "American Top 10" to reflect the change.
