Out-Of-Home advertising, which includes billboards and street marketing, is expected to be worth more than $1 billion for the first time in 2018.

Out-Of-Home advertising, which includes billboards and street marketing, is expected to be worth more than $1 billion for the first time in 2018.

The growth will largely come on the back of the rise in digital outdoor marketing, which is likely to account for 55 to 60 per cent of the entire OOH market's revenues by 2020, Dentsu Aegis Network's OOH advertising agency Posterscope managing director Bryan Magee predicts.

This will see the spend for advertising in this sector increase by more than 7 per cent year-on-year from $963 million in 2017 to $1.03 billion in 2018.

While this represents a slowing in digital outdoors spends, it's due to a maturing of the market - the take up has been particularly strong in Australia.
