Answer 1

Answer:

Step-by-step explanation:

Commercial advertising in Argentine television (including cable channels operated from the country itself) is limited to 12 minutes per hour. In-programme advertising is allowed, but counted toward the 12-minute quota, means that if a 60-minute show has 2 minutes of in-programme advertising, the commercial breaks have to be limited to 10 minutes for that specific hour, otherwise the station might face a fine. Promos for future television programs are considered as an advertisement, and also counted within the quota. Argentine television channels used to be required to separate advertising from the rest of the programming using bumpers with the text "Espacio publicitario" ("Advertising space") from September 2010 to May 2016.

From March 2014, advertisements shown on Argentine television began to use the phrase "Aviso publicitario de producción nacional" (Advertisement for domestic product) and "Aviso publicitario de producción extranjera" (Advertisement for foreign product) for local and foreign advertisements, respectively. Also, advertisements for alcoholic products had the warning "Beber con moderación. Prohibida su venta a menores de 18 años" (Drink in moderation. Do not sell to persons under 18). The warning was not used in alcohol advertising before 1997.
