Mobile-based music recognition service Shazam has arranged a new $30 million investment (around £20 million), which values the company at over $1 billion (£663 million).

The company has over 100 million active mobile users per month and has seen its app downloaded over 500 million times.

Shazam, which enables users to identify or ‘tag’ music tracks and learn more about TV shows via a smartphone app, has predicted the music artists that it expects will ‘break’ during 2014.

Overall, more than 400 million people use Shazam worldwide, with more than 15 million Shazam searches taking place every day.

Media engagement company Shazam, which offers a mobile-based music identification service, says its free mobile app has now been used more than 10 billion times to identify and ‘tag’ songs, television shows and TV ads.

The 10 billionth song was ‘Applause’ by Lady Gaga, which was tagged on an iOS device in the US state of New Jersey.

We start this week's podcast by talking about an Android security risk - before moving on to new 4G services from EE, a drop in Nook tablet prices and a couple of quarterly results that disappointed the stock market.

In addition we discuss insurance complaints, Bluetooth Smart technology, a new multi-million investment in Shazam and some research about the future of apps.

America Movil, which is Latin America’s largest mobile telecom network operator, has invested $40 million in mobile music recognition and media engagement company Shazam.

The money will help accelerate Shazam’s growth as well as funding the development of new products.

Recent figures released by ABI Research have prompted the market intelligence company to ask whether Google is losing control of the Android ecosystem.

At first glance, Android dominated smartphone shipments for the final quarter of 2013. ABI Research says 77% of the 287 million smartphones shipped in Q4 2013 were running Android.

After initially suffering from slow pick up by consumers, 4G has begun to accelerate, and is now well on the way to the forecasted one billion subscribers by 2017. In fact EE, owner of T-Mobile and Orange, recently announced the addition of 493,000 new 4G customers to its existing base of 1.2 million.

A new report has highlighted the issue of poor mobile phone coverage in rural Sussex villages. BBC Sussex invited me onto their ‘Sussex Breakfast’ radio show to explain what could be done - and, as usual, I made enough notes for a lecture rather than a three-minute interview.

Here’s what I would have liked to have said if I’d been given a disproportionate amount of time to talk.

Great news for mobile phone users. Ofcom’s new rules preventing unexpected mid-contract price rises came into force last week, which means UK consumers can no longer be surprised by their subscription charge increasing while they’re still locked into a minimum-term deal.

This week, new Ofcom rules came into force. They’re designed to avoid unexpected price rises during the minimum term of a mobile phone contract. Yes, just because you signed a fixed-term contract doesn’t mean the charges can’t increase. Networks said they needed this option in case of inflation or regulatory changes. Customers felt trapped.

Iain Graham, James Rosewell and Mark Bridge return to review their mobile industry predictions from last year. Which mergers, partnerships and developments did they forecast correctly... and which didn’t work out as planned?

Later in the programme, the team anticipates some of the topics that will be hitting the headlines during 2016.

Mark Bridge learns about the mobile technology trends at Mobile World Congress 2015 by chatting to James Rosewell of 51Degrees, Dr Kevin Curran from the IEEE and Chris Millington of Doro.

They talk about wearable devices, wireless charging, mobile operating systems and much more... including some of their favourite products from the exhibition.

We're taking a look back at the biggest mobile industry news stories from February 2015, including allegations that the UK's security service tried to breach SIM card security by hacking into one of the world's biggest SIM producers.

We also talk about the planned BT and EE merger, the creation of two new UK virtual networks, some acquisitions in the mobile payment arena and a new Ubuntu smartphone.

In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

We're back with a month of mobile industry news, including takeover talks and takeover rumours. O2 and Three are said to be discussing a merger... but is there any truth in the suggestions that BlackBerry could be up for grabs?

We also discuss Apple's record-breaking quarterly figures, the highlights of CES and the launch of Microsoft Windows 10, as well as saying farewell to the current version of Google Glass.
