Countdown to Extinction was released on July 14, 1992, through
Capitol Records and debuted at number two on the
Billboard 200 with first week sales of 128,000 copies. It was prevented from entering the chart at number one because of
Billy Ray Cyrus' long chart-topping reign with
Some Gave All. The album was acknowledged as the band's commercial breakthrough, and according to authors Pete Prown and Harvey P. Newquist, Megadeth "reached the heights of popularity and critical acclaim" with this particular record. Two years after its original release,
Countdown to Extinction was certified
double platinum and became the band's most commercially successful album, confirming that they had retained their audience in the wake of
grunge. The record was nominated for
Best Metal Performance at the
1993 Grammy Awards, while the album's title track won the
Humane Society's
Genesis Award for raising awareness for animal rights issues. The record enjoyed similar chart success outside of the United States. It managed to peak within the top 5 on the charts in the
United Kingdom and
New Zealand, and charted for eight weeks on both of them. It also entered the top 10 on the
Japanese and
Norwegian albums chart, while it charted slightly lower in several other countries as well. and received a silver award from the
British Phonographic Industry for having a shipment of 300,000 copies. The album was also eventually certified Gold in Japan and sold 100,000 copies. Asked how does he think that the album has aged, Dave Mustaine responded: "I think it's timely and timeless at the same time, and I think that's one of the most difficult things for a musician to do. Very few records in our genre are like that. Musically it's heavy and the lyrics are very symbolic." In the liner notes of the album's 20th anniversary edition, music journalist Kory Grow wrote that "thanks to a perfect balance of hard-rock song structures, epic choruses, and fleet-fingered guitar work,
Countdown to Extinction became an instant classic, benefiting from copious
MTV and radio play."
Artistdirect editor in chief Rick Florino called the album a "seminal" release and commented that it "changed the game by preserving the band's thrash intensity and impressive technical prowess, while dropping some of the biggest hooks the genre had ever seen". In a retrospective review of the album, Craig Hayes from
Popmatters wrote that
Countdown to Extinction's "status as a gateway metal album is indisputable" and its "popularity speaks volumes about its significance in the metal canon". ==Touring==
