Blackberry crumbles -

Blackberry sales have practically died in the key markets of US, China, Spain and Japan and only Britain and Canada keeping sales afloat.

New data from Kantar Worldpanel ComTech indicates that Blackberry is rather old fruit in most parts of the world now.

The latest data for smartphone sales for the three months to the end of October 2013 shows that the company's share of sales in the US fell to just 0.8 percent.

In China, Spain and Japan, its share fell to less than a tenth of a percent – a figure so low that Kantar records it as zero.

It seems that BlackBerry sales have collapsed as the outfit tried to sell itself to a private equity group, and then to raise $1 billion. The firing of chief executive Thorsten Heins, who had only been in place since January 2012 could not have helped much.

Blackberry's largest sales share, of 3.3 percent, was recorded in the UK.

What might be very depressing for Blackberry is that it was outsold by Windows Phone handsets in every market reported by Kantar, despite having launched its Z30 handset in September to add to its portfolio.

Meanwhile the results also have bad news for Apple. Its share of sales was just 15.8 percent, compared to 20.8 percent a year before.

The only bright star on Apple's horizon has been Japan with iPhone sales making 61.1 percent of the total in the quarter, and Android sales 36.2 percent.
