However, the 2001 first-half figure of €151m was a particularly buoyant one, compared with the first half of 2000, which had ad revenues equivalent to €134m.
NNI chairman Gavin O'Reilly, who is also chief operations officer of UK and Irish publisher Independent News & Media, said: "A spend of €133m in a period of six months is a clear expression of advertisers' confidence in newspapers as the number one medium in which to advertise goods and services."
He added: "More than 2.5m adults read NNI newspapers for their diet of news, views and current affairs. In this time of economic uncertainty it is necessary, now more than ever, to recognise the strengths of NNI titles, in terms of delivering a strong, loyal audience."
NNI represents nine Irish publishers and newspapers such as The Irish Times, The Irish Independent, The Irish Examiner, Sunday Business Post and Sunday World.
