Sisu became a favourite of Finns in the 1930s with very little advertising. The candy was particularly recommended for singers, orators and smokers, in practice it was a popular breath refresher and cough medicine. In the 1950s and 1960s, advertisements for Sisu could be seen in the local press, occasionally in nationwide newspapers, such as
Suomen Kuvalehti. The same advertisement images were used for several years, sometimes even for several decades. A new era began in advertising in the middle of the 1970s, when Sisu began to be advertised on television. The classic advertisement with the slogan "In the beginning, there was a
swamp, a
hoe and Jussi" was made by the advertisement company Lintas. The advertisement was an instant favourite among the Finnish public, and it was even broadcast in the 1980s. In the late 1980s, owned by
Rettig Group, advertising Sisu was closely connected to
ice hockey. The new owner Leaf also continued with the ice hockey theme. Sisu's ice hockey campaign culminated in Finland's world championship in ice hockey in spring 1995. Sisu ice hockey cards came to the Finnish market in 1993. The cards were published until 1996. On Sisu's 70th birthday in 1998, celebratory advertisements featured the mountaineer
Veikka Gustafsson. Gustafsson, along with
Patrick Degerman, had been the first to climb one of the tallest mountains on the
Antarctic. The mountain was named
Mount Sisu. Advertising of Sisu has been closely attached to rock music festivals since the launch of the Sisu Horna candy in 2002. In 2007, Sisu began sponsoring the
power metal band
Sturm und Drang, founded in 2004 in
Vaasa and consisting of
Finland-Swedish young musicians from 16 to 17 years. ==Different flavours of Sisu==
