The song gradually became something of a pop standard. An episode of
The Muppet Show produced in 1977 and broadcast early in 1978 featured
Rowlf the Dog singing the song to a puppy. In 1978, it was featured in the closing scenes of BBC radio's ''
The Hitchhiker's Guide to the Galaxy'', and was repeated for BBC's 1981
TV adaptation of the series. In 1988, Armstrong's recording was used in the film
Good Morning, Vietnam (despite its setting in 1965, two years before the song was recorded) and was re-released as a single, reaching number 32 on the
Billboard Hot 100 chart in February 1988. It charted at number 1 for the fortnight ending June 27, 1988, on the
Australian chart. When the
ABC television sitcom
Family Matters premiered in 1989, Armstrong's version of "What a Wonderful World" was used as the show's theme song. However, after the fifth episode, it was replaced by the original song "As Days Go By". In 2001, rappers
Ghostface Killah,
Raekwon, and
the Alchemist released "The Forest," a song that begins with three lines of lyric adapted from "What a Wonderful World", altered to become "an invitation to get high" on marijuana. The rappers and their record company, Sony Music Entertainment, were sued by Abilene Music, the owners of "What a Wonderful World". The suit was thrown out after Judge
Gerard E. Lynch determined that the altered lyric was a parody, transforming the uplifting original message to a new one with a darker nature. After it was released digitally, Armstrong's 1967 recording had sold over 2,173,000 downloads in the United States as of April 2014. In 2021, it was ranked at No. 171 on
Rolling Stones "Top 500 Best Songs of All Time". == Charts and certifications ==
