In the first half of 2008, the company expects its net advertising revenue to be flat, compared to a 1% drop across the whole market.
ITV's share price showed little reaction to the update, moving down 0.3% from yesterday's close to 62.6p.
Michael Grade, executive chairman, reiterated that the turnaround plan outlined in September last year remains on track.
He said: "The forecast for the first half shows us outperforming the UK television advertising market -- the first time this has happened since 2000.
"Across ITV as a whole we are sustaining operational momentum in all parts of the business."
The company had a positive first quarter with overall revenues up 3% year on year to £492m and advertising revenues up 2%.
But while ITV1 increased its number of adult commercial impacts by 1.5% to 81.3bn, the ITV family of channels lost ground on Grade's key share of commercial impacts (SOCI) target.
Its SOCI fell from 41.8% a year ago to 41.3%, still well above the 38.5% target Grade wants it to exceed in 2012.
Content revenues climbed by 7% to £133m. Growth in this area is another of Grade's three key 2012 targets -- he wants the content division to double its annual revenues to £1.2bn.
ITV today announced the acquisition of Scandinavian TV producer Silverback for a sum of up to £8.8m, dependent on meeting performance targets over three years.
ITV's global content revenues have been driven by such acquisitions as well as organic growth and are up 41% for the first quarter to £58m.
The company also provided statistics on usage of its consumer website . User numbers for April were up 35% year on year to 6.2m, while the number of videos viewed on the site is up 76% since January to 9.9m.
Online revenues were up 13% to £9m.
Grade's third key target is for ITV's consumer business to take its online revenues to £150m by 2010, from a total of £47m in 2006.
Earlier this week, ITV announced that Nicky Buss is to quit as customer relations director at ITV for personal reasons. She joined ITV in 2006 as advertiser development director and headed branded-content initiatives such as 'Beat: Life on the Street' and 'Dog Rescue'.
Her departure coincided with the arrival from AOL Europe of Chad Wollen as director of marketing Strategy, reporting to David Pemsel, ITV's group marketing director.
At AOL Europe he was director of insight, foresight & media innovation.
