Australian newspapers are expected to account for less than 30% of the country's overall ad revenues this year, compared with 41.8% in 2000, according to IBISWorld. Meanwhile, revenue for newspaper publishers is expected to decline by 4% this year. "Declining circulation over the past five years, caused by time restraints, the rising popularity of new media like the Internet, pay-TV and mobile devices, and competition from consumer magazines, has continued to have an adverse effect on the industry," said Karen Dobie of IBISWorld.
