Total advertising revenue for the first 10 weeks of 2013 were 15.6 percent below the same period in the prior year, Johnston Press said.
Pretax profit fell to 12.6 million pounds ($19 million) on an underlying basis in the year ended Dec. 29, from 28.4 million pounds a year earlier.
Revenue fell 12 percent to 328.7 million pounds.
The group that publishes 13 daily newspapers and more than 230 weeklies, said advertising revenue declined 12.7 percent to 201.9 million pounds.
