UK broadcaster ITV has said that revenues grew 14% to £755m in the first quarter of 2016, but warned that Brexit fears are impacting the television advertising market.
In a trading update, the company said that sales growth was driven by a strong performance at its television production arm, ITV Studios.
Non advertising revenue rose 34% to £428m, and ITV said it expects to deliver profit growth in the first half of the year.
However, chief executive Adam Crozier warned that this is against the backdrop of uncertainty in the UK advertising market, which the broadcaster has experienced since the debate over Brexit began.
Nevertheless, ITV described the UK television market as "robust" and flagged its pipeline of new and returning programmes such as Victoria, Cold Feet and The Voice as prospective drivers of growth over the year and going into 2017.
ITV's main channel share of viewing was up 3% in the first four months of the year and its online viewing consumption grew by 22% year-on-year.
Mr Crozier added that he expects ITV Studios to deliver double-digit revenue and profit growth this year.
