Happy 50th Birthday, AT40!
American Top 40 was created by Casey Kasem in 1970. Seacrest debuted as host of the program in January 2004, and continued the tradition of counting down the Top 40 songs and interviewing the biggest stars in entertainment. The program was also revolutionized with added technology — building on the interactive quality of at40.com, the audience was allowed to vote for their favorite songs, enter contests for concert flyaways and communicate directly with Seacrest. Today, American Top 40 with Ryan Seacrest continues to be the No. 1 countdown show in the U.S. and can be heard on nearly 500 radio stations worldwide.
