Yes, that’s right. The Swedish Europop foursome — Benny Andersson, Björn Ulvaeus, Agnetha Fältskog, Anni-Frid Lyngstad — that spawned the hits “Dancing Queen,” “Mamma Mia” and “Waterloo,” helped pioneer reality television.

Back in the 1970s, their songs seemed to be everywhere. Britannica called the band one of the top commercial successes in pop music’s history. The group became famous after winning Eurovision, an international talent contest, in 1974. They went on to sell more than 380 million albums and singles to a global market, according to The Sun. 

The performers — known for their outrageous costumes — disbanded in 1982, in part, to pursue solo careers. Fältskog married Ulvaeus in 1971, and Lyngstad and Andersson tied the knot seven years later, according to Express. The relationships struggled during the band’s success and both couples eventually divorced. While the uncoupling inspired the song, “The Winner Takes It All,” ultimately the separations took its toll on the group.

ABBA’s foray into reality programming happened a few years prior to the band’s demise. Their fourth studio album, “Arrival,” “arrived” in 1976 and it cemented their status as bona fide international stars. It included their signature tune, “Dancing Queen,” the only effort they released that hit No. 1 on the American charts, according to the Guardian.
