7 goals had only been put past Brazil in a single match once before, when Yugoslavia beat them 8-4 in a friendly on 3 June 1934.
No-one had ever scored seven in a FIFA World Cup semi-final though; the previous record was six, with three teams - West Germany being the most recent in 1954 - having managed that.
Low's side also registered the highest-ever margin of victory in the last four, with five goals having held the record prior to today.
Only once before had seven goals been scored in a knockout match, when Austria beat hosts Switzerland 7-5 in the highest-scoring World Cup match of all time back in 1954. That was also the only previous occasion, prior to tonight, that a World Cup host team had conceded seven goals in a single match.

Brazil's national media quickly dubbed the football team's 7-1 defeat to Germany on Tuesday the "Shame of Shames" and the most humiliating defeat in the squad's history.
Newspapers and TV commentators called the defeat the "Mineirazo," an allusion to the Mineirao Stadium in Belo Horizonte and Brazil's traumatic FIFA World Cup™ defeat at home in 1950 known as the "Maracanazo."
The sport's daily Lance called Tuesday's crushing loss "The Biggest Shame in History."
"The Maracanazo becomes nothing and literally a thing of the past," the newspaper said on its website.
The top of Folha de Sao Paulo newspaper's website was titled "Historic Shame" after Brazil suffered its worst defeat in the national team's 100-year history.
"Brazil is humiliated again trying to win the cup at home," the daily said.
The G1 news website quotes Brazilian manager Luiz Felipe Scolari saying "catastrophic result".
Its sister sports publication Globoesporte.com called it the "Shame of Shames".
