Barnes & Noble and Microsoft have agreed to end their NOOK eBook partnership.

The two organisations formed NOOK Media LLC in 2012, combining Barnes & Noble’s digital eBook and College education businesses into a new company that was 17.6% owned by Microsoft.

Samsung Electronics America and the Nook Media subsidiary of Barnes & Noble have announced a partnership to develop Samsung Galaxy Tab 4 Nook tablets.

The co-branded tablets will combine Samsung’s Android-powered Galaxy Tab 4 hardware with customised Nook e-reader software, making it easier for users to download and read eBooks, magazines and newspapers.

The UK Advertising Standards Authority has upheld a complaint about recent advertisements for discounted Barnes & Noble Nook eBook readers.

In April Barnes & Noble cut the price of the basic Nook reader from £79 to £29, advertising the product’s availability at Argos, Asda, Blackwell’s, Currys, Foyles, John Lewis, PC World, Sainsbury’s and Very.

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.

Last month bookseller Barnes & Noble announced that its Nook tablets wouldn’t be produced as own-brand devices any more.

Although it would maintain the production of its eBook readers, the next generation of Nook colour-screen tablets would be co-branded with third-party manufacturers.
