'SYTYCD' trio  Host Cat Deeley, judge and executive producer
Nigel Lythgoe and judge Mary Murphy of "So You Think You Can
Dance." (Mathieu Young / Fox)  Fox's "So You Think You Can
Dance" has ridden the wave of dance show popularity and will
complete its 10th season with Tuesday night's finale.  Along
with creating successful dancers and choreographers, the show
(also known as "SYTYCD") can lay claim to introducing some big
musical artists. Both Lady Gaga and Katy Perry had their first
breakout national performances on the show.  Other artists
who've been on the show early in their careers include Adele,
OneRepublic and Goldfrapp. The show is also receiving more
recognition this year with seven Emmy nominations, including one
for host Cat Deeley, and a 42-city tour kicking off Oct. 1.
Executive producer Nigel Lythgoe, who along with Simon Fuller
created "SYTYCD," is also one of the judges. We caught up with
him to talk about what's changed in the show's first 10 seasons
and where the dance world is now.  INT
