Schibsted-owned Aftenposten raises the paywall. From 12pm today (about now) non-subscribers can only read eight online articles a week before they have to pay for online access.
Digital subscribers have to pay about £20 per month (with today's exchange rate). Most comments I've seen on the story so far are calling for a Spotify-solution that would allow you to subscribe to all Norwegian online newspapers (or at the very least Schibsted's Norwegian newspapers) for one price - akin to what Piano Media operates in various countries - instead of each news site raising separate paywalls.
