At the beginning of the 21st century I moved from Vodafone to work for its Vizzavi multimedia portal, wooed by talk of context-specific advertising that would one day use a customer’s location and search history to ensure any ads were precisely targeted. And I’m not the only person who’s been seduced. Consumers, ad agencies, client companies and mobile networks have all been promised much by mobile marketing.

This week there was only one set of financial results that attracted the mainstream tech media. Apple reported the first drop in quarterly profit for several years as figures fell by 18% to around £6.1 billion. On the positive side, it made around £6.1 billion profit. It also announced dates for its developer conference in June and promised a new version of iOS.

UK telecoms regulator Ofcom is asking companies to take part in a trial of ‘white space’ wireless technology.

White space technology takes advantage of unused gaps in frequency bands, enabling wireless internet services and machine-to-machine connections to operate without interference.

A new report from the International Data Corporation says more smartphones were shipped in Q1 2013 than feature phones, which is the first time smartphone shipments have dominated.

Overall, it reckons the worldwide mobile phone market grew 4% year-on-year in the first three months of this year. IDC says manufacturers shipped 418.6 million mobile phones in the quarter, of which 51.6% were smartphones.

ZTE Corporation says its profits rose by 35.9% in the first quarter of this year, helped by the sale of some company assets.

Net income was up to 205 million yuan (£21 million), although quarterly sales were down 2.8% to 18.1 billion yuan (£1.9 million).
