The Eagles changed the game on February 17, 1976 with Their Greatest Hits (1971-1975).

Meant as a way to boost record label revenue while the band was making Hotel California, Their Greatest Hits (1971-1975) was a monster. The collection has a unique place in music history. In fact, it was the first release to be Platinum certified (1 million copies sold) by the RIAA.

Of course, this set would go on to sell far more than 1 million copies. In honor of its release anniversary, here is Their Greatest Hits (1971-1975) by the numbers.
