ITV's chief executive Adam Crozier has questioned the effectiveness of online advertising, saying that while brands investing in digital "might look like they're being more efficient on paper" they are not seeing the expected results. Speaking at the brand's annual results conference yesterday, Crozier said that numerous "big advertisers" have voiced their concerns when it comes to online advertising and measuring its effectiveness.

Deloitte's CMO practice leadership has weighed in on a recent CMO Survey report, sponsored by the consultancy, conducted bi-annually for the past eight years by Duke University's Fuqua School of Business marketing professor Christine Moorman. The key findings of the report were a mix of positive and negative -- with the upside being increased marketing spend and the downside focusing on the relative lack of results.

Advertisers are being promised the ability to bridge the gap between online and offline customer data based on where they are in the real world using beacon data following a tie-up with Opera Mediaworks and Unacast. It's being pitched in as more effective way to retarget ads to people on the move, which until now has primarily be done using less accurate GPS data. Now, data sourced from beacons as someone moves down an aisle or looks at a product in-store is being used to retarget ads.

Internet "trolls" who create fake social media profiles could face charges, say guidelines being proposed for prosecutors in England and Wales. The Crown Prosecution Service says adults should be charged if they use fake social media IDs to harass others. Cases would also follow if posts were indecent, grossly offensive or so false they caused distress and anxiety. The CPS is amending its guidelines to keep its staff up to date with modern crime. A six-week consultation on the proposed changes has now begun.

"Guardian" editor Katharine Viner has said she wants to persuade more readers to become paying "members," but insisted there are no plans for an online paywall. Press Gazette understands that a revised Guardian membership offer could include some elements of premium content, but that a decision has yet to be made. Viner was speaking at the British Library in London yesterday morning at a conference run by Newsworks (formerly the Newspaper Marketing Agency).

The number of consumers making contactless payments globally will reach 148m this year, with Apple and Samsung accounting for nearly 70% of new customers. The figures, from Juniper Research, also estimate that 16m users will make contactless payments via mobile handsets in Western Europe during 2016. The industry has already received a strong push from the launch of Apple Pay and Samsung Pay in selected key markets. Apple Pay launched in the UK in June 2015.

Ikea is reviewing its estimated EUR400 million (GBP312 million) global media-buying arrangements with at least five agency holding groups. It is not clear whether Ikea plans to consolidate its buying with fewer agencies. WPP's Group M is believed to be the agency group that has the single largest part of Ikea's business, but all of the five biggest ad groups handle the Swedish furniture giant in different territories.

An end to 94 years of BBC self-regulation by scrapping the BBC Trust has been proposed by an independent report calling for "fundamental reform" of the way the corporation is governed. The Clementi report -- published on Tuesday, the day before the culture secretary, John Whittingdale, is set to give a keynote speech on the BBC -- forms part of the government's review of the BBC's royal charter. It recommends that the communications regulator Ofcom should handle all regulatory oversight of the broadcaster.

ITV increased underlying pre-tax profit by 18% to GBP865m in 2015 and predicts it will outperform the UK TV advertising market this year, with attractions including the Euro 2016 football tournament. The UK's biggest advertiser-funded broadcaster on Wednesday reported a 15% increase in revenue to GBP2.97bn last year, despite a decline in audience share for its flagship TV network.

A week after launching, the Google-led Accelerated Mobile Pages (AMP) initiative has raised more questions than answers for publishers concerned over its capacity to generate advertising revenue. Despite the teething problems, it is too early to chuck out the baby that is AMP with the bath water, and get overly concerned. It is clearly in its infancy in terms of its offering for advertisers and publishers have bought into the principle of offering Web users a faster mobile experience.
