LONDON, March 7 (Reuters) - Britain's ITV reported a 32% drop in full-year adjusted operating profit to 489 million pounds ($623 million) on Thursday, reflecting a tough advertising market and investment in its ITVX streaming service.

Chief Executive Carolyn McCall said ITV was "well placed to grow profits from here", forecasting continued progress in its Studios business after a record 2023, a drop in funding for ITVX after last year's peak and cash generation from advertising.

The broadcaster, which had its biggest drama success in over a decade in January with "Mr Bates vs the Post Office", said it was on track to deliver at least 750 million pounds of digital revenue by 2026.
