The channel broadcasts in seven languages simultaneously, including English, German and French, with a schedule of 30-minute programmes covering news, current affairs, business and sport.
Rivas, who joined the channel at launch in January 1993 as chief editor, said: 'EuroNews is a major player among news channels in Europe. We intend to reinforce this role and develop it outside of our continent. EuroNews is a unique and fascinating project, because it's the only information channel offering news from a European, rather than a national, perspective.'
Rivas has been acting editorial director since January. Before joining EuroNews, he worked with Spanish state broadcaster TVE as its correspondent in Moscow and Budapest. Rivas has also worked for the Spanish weekly magazine El Tiempo and the country's press agency EFE.
EuroNews was launched by a consortium of European public service broadcasters and has an editorial team of 160 multilingual journalists.
