Here’s an edited transcript of our new monthly podcast, broadcast on 30th January 2015.

If you’d like to join 51Degrees in sponsoring the podcast and returning us to weekly programmes, please get in touch via our website. Now, on with the show.

New figures from Strategy Analytics show that Samsung and Apple each produced 74.5 million smartphones in the final quarter of 2014, giving each of them just under a fifth of the total smartphone market.

It’s the first time the two companies have been this close with quarterly shipments since the end of 2011.

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.

Last summer, Samsung announced the high-spec Samsung Z, which it described as “the first commercially available smartphone powered by the Tizen platform”. However, the launch was postponed and the phone’s release apparently cancelled in favour of a focus on lower-spec devices.

Samsung has now announced a new Tizen smartphone: the Samsung Z1.

Patent strategy specialist RPX Corporation says one of its subsidiary companies has bought approximately 4,000 patents from Rockstar Consortium.

Rockstar was formed three years ago to acquire around 6,000 technology patent assets from Nortel.
