If you watched High School Musical 2 on Friday night Aug. 17, 2007, you had lots of company.
The Disney Channel said more than 17 million people were watching. That makes it the most-watched basic cable telecast of all-time.
That also means High School Musical 2 is the number-one original movie on basic cable.
Tom Selleck’s Crossfire Trail, which aired six years ago on TNT, used to hold that record.
