Online advertising revenues increased 4.9% year on year to reach $2.2billion in Q1 2019, according to latest IAB data.

IAB CEO Gai Le Roy said the market was "tough across all platforms" but that "bright spots" remain buoyant. She said increased government/political spend would also show in second quarter figures.
Search and directories maintained a 44% share of online advertising expenditure, standing at $977.6m for the quarter. Classifieds reached $426.2m, a 20% share of spend and general display advertising is now 36% of spend at $799m.
Video represented the largest share of general display expenditure at 46%, followed by content, native and infeed at 35% and standard display formats at 18%. Each of these segments has a component of mobile advertising expenditure with mobile advertising making up 66% of total general display expenditure, an increase from the December 2018 quarter.
