BARCELONA (Reuters) - British broadcaster ITV (LON:ITV) reported a 5 percent drop in adjusted full-year earnings, reflecting the tough advertising environment facing new chief executive Carolyn McCall.

ITV, the country's biggest free-to-air commercial network, reported core earnings of 842 million pounds on Wednesday, with a drop in ad revenue partly offset by underlying growth in its studios business.


McCall, who joined ITV from airline easyJet (LON:EZJ), said the company's operational performance in 2017 in a challenging environment was strong, and its viewing performance and studio gave it a solid foundation to build on.
