Facebook has apologised after it placed adverts on a publicly funded TV network’s website without permission.
People who visited the website of Danish broadcaster DR via the Facebook iOS app were served with unauthorised third-party advertisements.
A spokesman for the broadcaster said it had still not been made aware of how many users had been affected.
Facebook said the incident was caused by a coding error that had since been resolved.
News site Digiday reported that the issue first came to light last week, when a user complained about being targeted with adverts while visiting DR’s website.
DR is publicly funded via a licence fee and does not allow ads on any of its platforms.
A spokesman for Facebook said a coding error “caused some people to see interstitial ads within news content in the Facebook app”.
“We apologise for any inconvenience this may have caused,” he added.
