A new report reveals that the boom in online advertising over the past quarter is in large part due to the rise of mobile and video advertising.

Record breakers

The data comes courtesy of the latest Interactive Advertising Bureau's Online Advertising Expenditure Report, which was conducted by PricewaterhouseCoopers.

Total expenditure for the fourth quarter of 2014 was $1.2 billion, a rise of 7.1% year-on-year.

While overall expenditure for 2014 topped US$4.6 billion, marking a 16% year-on-year increase.

Mobile march

Mobile advertising continues to gain ground, netting $762 million over 2014. Or a 118% increase year-on-year.

Video advertising was also no slouch, accounting for $237 million – a 52% boost year-on-year.

FMCG is the biggest spender on video ads, making up 16.5% of that category's total for the full calendar year.

Display gains

Elsewhere, retail posted its strongest quarter in Q4 and now owns 10.9% of General Display Advertising. 

General Display advertising was valued at $1.4 billion over 2014, with Classifieds at $929 million and Search and Directories at $2.3 billion.
