How is political defined? What happens in the US is that if certain financing is unavailable to be used in a certain way, like direct support of a candidate or party, then that money is shifted into “issue advertising” which presents a topic of political disagreement to favor one side over another. Within the information domain of a political debate, there may be human activities that are non-political but political organizations disguise themselves within, for example, adoption services in the abortion debate. Many messages, such as car advertising have an implicit political message that public funding of roads is positive and liberating. Maybe Norway has the line between political and everything else figured out or maybe there is a cultural definition that makes it easier, but banning political advertising seems very difficult.

Seems simple enough to me: if it's funded by a political party or candidate, it's a political advertisement, regardless of the content. There are always ways of illegally hiding candidates' expenses, but most of the time it should be obvious who funded an ad opposing or promoting a politician.
