What time is it? Why it’s the 20th anniversary of High School Musical!

20 years ago today, Disney Channel premiered their hit Disney Channel Original Movie (DCOM), High School Musical, and little did any of us know what a phenomenon it would become. It premiered to over 7 million viewers, launched two sequels and an eventual spin-off series, had a best-selling soundtrack album and sold out concert tour, and launched some of its’ star into stardom.

Below, some of the cast are posting throwbacks in honor of the anniversary.
