It was the most popular program in the history of Polish television and at the same time first telenovela (Latin American soap opera) screened in Poland (1986). On average it was watched by more than 81 percent of the total viewing audience (sometimes as much as 92 percent).
In the late 1980s, thanks to "perestroika", Soviet citizens were allowed to own a small piece of land. Under the immense popularity of the series, those pieces of land were very often semi-seriously referred to as "fazendas", which is a Portuguese word for 'farm', often used in the series for the large plantations, where the story was taking place.
The show was incredibly popular in the former Soviet Union, even among the children. So much so that during its airing and afterward it became a common practice at many schools for the prettiest girl in each class to be referred to as "Isaura". Some appropriate students could also be "named" after other characters of the series.
