The slow painful death of print advertising has caused The Daily Mail to cut this year's profit forecast

The publisher of The Daily Mail has cut its full-year profit forecast to reflect the "challenging print advertising" market, and difficult financial market conditions.

The Daily Mail and General Trust (DMGT) said in $4 that its 2015 outlook will now be towards the "lower end of market expectations."

Underlying group revenue dropped 1% in the three months to the end of June 2015. DMG Media, in which The Daily Mail sits, saw a 5% decrease in revenue in the period.

Circulation revenues fell 3% due to lower volumes, although both The Daily Mail and The Mail on Sunday grew their UK market share - to 23.4% and 22.1% respectively. Significantly, the Mail on Sunday overtook The Sun on Sunday to become the UK's biggest Sunday newspaper in May, $4 The Sun is still the UK's biggest daily, with a circulation of 1.8 million in May, $4, compared to The Daily Mail's 1.7 million.

DMGT said there was a "marked deterioration" in the UK print advertising market, which is negatively impacting the group. $4 to £2.7 billion ($4.2 billion.) Meanwhile, digital ad spend is expected to grow 12% to £8.1 billion ($12.6 billion.)

The success of Mail Online, which grew digital advertising review by 8% year-on-year to £1 million ($1.6 million) partly offset the £7 million ($10.9 million) - or 15% - decline in print advertising at The Daily Mail and Mail on Sunday in the quarter. However, overall, advertising revenues across the Mail business as a whole were down 9%.

The MailOnline boosted its global monthly unique visitors by 25% year-on-year to 211 million.
