Speaking at Media 360, Brooks warned that the proliferation of digital media poses "big questions" for traditional media.
And he warned that the problems facing local press - marked by double digit percentage declines in ad revenues and numerous newspaper closures - "is not isolated" and could be a sign of problems "blowing through the rest of media".
While hailing the advent of digital - highlighting, for example the success of GN&M in North America in recent years - Brooks warned that the industry should not be in too much of a hurry to find new models at the expense of current offerings. He said that "the problem with revolutions" is that "old models get broken before a new one is in place".
Meanwhile, Phil Georgiaidis, chairman, Walker Media, issued a warning to delegates about focusing too much on cross-media campaigns.
Highlighting that "media consumption has never been wider" he warned that the industry has sometimes had a tendency to "house too much media in one place".
He added that a cross media approach "assumes" consumers will bother to edit all of the ads in a cross-platform campaign for a particular brand.
