The first half of this year saw 40% growth in the Irish digital advertising market with a total digital spend of €130m.  Mobile ad spend now accounts for 29% of total online ad spend. 

According to a report out this morning from PwC and IAB Ireland, this strong performance contrasts with the spend on other media, which grew by less than 1% in the same six months. 

“Device usage and second screens have very much driven the ad spend,” according to - IAB Ireland's Suzanne McElligott. 

“It has also grown across desktop, but the most dramatic and record growth is the takeoff of mobile, and that is up 132% in the first half of this year.”

Ms McElligott said the type of advertisers on mobile tends to be the same as might be seen on more traditional platforms – those categorised as fast-moving consumer goods – with retail and financial sectors all well represented in the sector.

According to Jide Sobo, head of mobile at media agency MEC UK, the type of ads used on mobile tends fall into two categories – those being banner ads and so-called ‘native’ adverts, where the ad looks similar to a website’s content.

“Particularly in things like Facebook, adverts that appear within the newsfeed tend to look quite similar to the other content that appears there,” he said. 

“And the idea is that those adverts should have contents or messages that are very relevant to you, and then they become less intrusive and consumers are much more likely to engage with that type of advertising.

Stock markets in Asia were mostly higher and the US dollar jumped in value after the Federal Reserve announced the end of its quantitative easing stimulus programme last night.

And because of what the Fed called "gradually diminishing" joblessness it's thought its shift away from aggressive monetary stimulus will mean a move towards the need for an eventual rise in interest rates from their current level close to zero.

The number of billionaires has more than doubled to 1,645 since the financial crisis, according to an Oxfam report. But as the ranks of those with 10-figure fortunes swelled, the gap between the rich and poor has widened rapidly, the report finds. 

Some findings: The world's richest 85 people own as much as the entire poorer half of the world. And they're getting richer fast: Last year, those 85 people grew $668 million richer each day. The combined wealth of today's billionaires has grown by 124% in the last four years to $5.4 trillion.

Samsung Electronics has seen its quarterly operating profit fall to its lowest level in more than three years because of slowing smartphone sales. The South Korean company said profit fell 60% to $3.8bn in the three months to September. 

Shares of the world's biggest smartphone-maker have lost nearly 20% of their value this year.

Samsung's mobile division, its biggest business, has been struggling to maintain its dominance against rivals such as Apple. The company has been forced to rely on sales from other parts of its business including semiconductors and other technology to offset smartphone losses. 

Samsung said market competition is "expected to further intensify".
