Ten entries ultimately qualified to compete in the final on 9 February 2013 where the winner was determined over two rounds of voting.

In the first round of voting, a public televote exclusively selected the top four entries to advance to the competition's second round—the Gold Final.

Performing during the show in position 13, "I Feed You My Love" was announced among the top 10 entries of the second semi-final and therefore qualified to compete in the final on 18 May.

Norway had won the contest on two occasions: in 1985 with the song "La det swinge" performed by Bobbysocks!

[2] The broadcaster has traditionally organised the national final Melodi Grand Prix, which has selected the Norwegian entry for the Eurovision Song Contest in all but one of their participation.

[4] All shows were hosted by Jenny Skavlan and Erik Solbakken and televised on NRK1 as well as streamed online at NRK's official website nrk.no.

The results of the semi-finals were determined exclusively by public televoting, while a jury also awarded one of the eliminated acts a wildcard to proceed to the final.

In addition to the public call for submissions, NRK reserved the right to directly invite certain artists and composers to compete.

[10] The seven acts and songs competing in each semi-final were revealed on 16, 23 and 30 January 2013, respectively, during the special show MGP Direkte, presented by Jenny Skavlan and Erik Solbakken and broadcast via NRK1 and online at nrk.no.

The results of the public televote were then revealed by Norway's five regions and added to the jury scores, leading to the victory of "I Feed You My Love" performed by Margaret Berger with 102,032 votes.

According to Eurovision rules, all nations with the exceptions of the host country and the "Big Five" (France, Germany, Italy, Spain and the United Kingdom) are required to qualify from one of two semi-finals in order to compete for the final; the top ten countries from each semi-final progress to the final.

On 17 January 2013, a special allocation draw was held which placed each country into one of the two semi-finals, as well as which half of the show they would perform in.

[22] An alternative broadcast of the final was also televised on NRK3 with commentary by the hosts of the NRK P3 radio show P3morgen Ronny Brede Aase, Silje Reiten Nordnes and Yngve Hustad Reite.

[25][26] The drummer on stage with Margaret Berger was Axel Tidemann, while the three backing vocalists were: Jorunn Hauge, May Kristin Kaspersen and Nicoline Berg Kaasin.

This jury was asked to judge each contestant based on: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.

The following members comprised the Norwegian jury: Suzanne Sumbundu, Henning Solvang, Martine Maribel Furulund, Simone Eriksrud and Harald Sommerstad.
