The brand is known in the United Kingdom, and other countries such as Mexico, by the popular 1990s 'ambassadors' advertisement Ferrero Rocher: "The Ambassador's Party" on YouTube.

Michele Ferrero, the credited inventor, named the chocolate after a grotto in the Roman Catholic shrine of Lourdes, Rocher de Massabielle [fr].

[7] The mechanised production process begins with flat sheets of wafer with hemispheres moving down an assembly line.

[7] A United Kingdom advertisement in the 1990s was based upon a party in a European ambassador's official residence, with the chocolates arranged into a pyramid and portrayed as a sophisticated treat.

[13] Ferrero Rocher is popular among immigrant communities in the United States due to its relatively low price compared with other luxury goods, along with its upscale appearance and marketing.

[15] Ferrero had spent USD $1 million and five years fighting Chinese firm Montresor, whose "Tresor Dore" chocolates were priced at one-third of the cost of the genuine Rocher; an April 2008 court ruling had previously ordered Montresor to cease production.
