Google has been named number one in FutureBrand's Global Top 100 list, which rates companies by their public perception and not just their financial worth. Thus, although Apple is the most valuable brand, according to the researchers, it drops to fourth place when brand perception is considered. ExxonMobil similarly drops from second position, in financial terms, to the 87th spot when perception is added to the equation. Microsoft and Walt Disney were named in second and third place.

Labour's Deputy Leader Harriet Harman has begun wooing adland ahead of next year's general election. She assured an ISBA lunch at the London's Dorchester hotel that the industry would have nothing to fear from an Ed Miliband-led government. Any such administration would not regulate through "knee-jerk" reactions, but would instead use organisations such as the ASA to bring in any change deemed to be in the public interest -- and hence, by definition, in the industry's best interests too.

Twitter has revealed its purchase of TapCommerce, a New York retargeting company, for $100m. The digital advertising start-up specialises in contacting people who showed an interest in a product or service but did not make a purchase. "Advertisers spend aggressively to get new users, but re-activating existing or previous users can provide just as attractive a return on investment," wroteTwitter's Vice President of Global Online Sales Richard Alfonsi in a blog post about the acquisition.

Teams across Ford are being called upon to speed up the delivery of services and content so the car marque can become more real-time -- not just in marketing and communications, but across the company. In marketing, the company is using real-time content seeded in social media to launch vehicles. It claims to have used this strategy, in combination with television and earned media, around the Champions League final to generate 500 pre-orders of the Mustang when it launched in Europe.

Britvic is calling a review of Tango's advertising account. The drinks brand has been handled since 2008 by Bartle Bogle Hegarty who will not be repitching for the business. BBH will continue to work for Tango's sister brands Robinsons, Fruitshoot and J20.

After a month of testing, which Twitter says went well, mobile-app install adverts will now be rolled out to news feeds. The mobile ads will provide links to Apple App Store or Google Play, where advertised apps can be downloaded. Such adverts are believed to now form the majority of Facebook's mobile advertising revenue. Twitter doubled its revenue in Q1 of this year to $250.5m, but has yet to post a profit.

Mobile advertising will overtake print advertising next year and then television in 2016, according to a forecast from eMarketer. It estimates mobile advertising will nearly double this year to hit GBP2.02bn, just below the GBP2.06bn forecast for print. However, mobile will grow a further 60 percent in 2015 to be worth GBP3.2bn -- half a billion pounds more than print. The year after -- 2016 -- mobile will be worth GBO4.46bn, a little over half a billion pounds ahead of television.

Three in four mobile consumers believe targeted adverts are an invasion of their privacy, according to a global research study from Publicis-owned Razorfish. The digital creative agency questioned 1,500 Millennial and Generation X consumers and found that with mobile, millennials were generally more interested in mobile payments and more likely to churn from a brand that gave a bad mobile experience. Overall, 84 percent said they prefer a brand to be useful rather than interesting.

The first UK campaign to use Microsoft technology which prevents consumers from seeing the same advert across multiple devices launched yesterday. Heineken-owned Bulmers has released its "live colourful" campaign with five different creative treatments for its five flavours of cider. Microsoft's creative sequencing technology can recognise users across different devices, from their Microsoft ID, and ensures that adverts are not repeated. The service is already available in the U.S.

Facebook is defending its secret recent psychological test that manipulated the news feeds of 686,000 users. Unwitting test subjects had their news filtered so they either received more positive or more negative updates. Facebook was keen to establish how this would affect each subject's mood when posting. Facebook has countered critics by saying it wanted to establish whether "emotional contagion" exists and how it affects people.
