NPO Nieuws was a 24-hour news channel operated by the NOS, the public broadcaster which supplies news and sports to all national public television and radio networks.

NOS also provides programming for the political channel, NPO Politiek en Nieuws.

A half-hourly version (15 minutes plus another 15 minute repeat) of the youth-oriented news programme NOS Jeugdjournaal also aired every day on NPO Nieuws.

At any point, the programming could have been interrupted for breaking news.

On 10 March 2014, Journaal 24 changed its name into NPO Nieuws.
