It’s the fourth ‘90s music video overall to reach a billion views, following Guns N’ Roses’ "November Rain," Nirvana’s "Smells Like Teen Spirit" and The Cranberries’ "Zombie."

Dolly Parton originally wrote "I Will Always Love You" in 1973, but it found huge success in 1992 when Houston recorded it for "The Bodyguard" soundtrack.

Houston's version of "I Will Always Love You" won the awards for Record of the Year and Best Female Pop Vocal Performance at the 36th Grammy Awards in 1994.

Houston’s version spent 14 weeks at No. 1 on the Billboard Hot 100.
