Bread, Milk, Tablets..

It's notable that one of the major aspects of technology that separates the UK and the US is that the US is yet to see any success in the grocery delivery market, whilst in the UK it's become the main way for many people to do the weekly shopping.

We all recall the ambitions of Webvan, and perhaps this variance shows the stark difference between the retail industry either side of the Atlantic.

But now, it is UK retailers who are following the lead of the likes of Barnes & Noble in looking to enter the tablet market.

The reason is simple, at one point the major supermarkets were accounting for well over half of all music and films being sold in the UK. However, that figure has fallen off a cliff and the supermarkets are keen to have it back.

This week sees the launch of the Tesco Hudl, and Sainsburys are also working on their own online entertainment services.

Of course, it has to be pointed out that Barnes & Noble's Snook has not been a huge success and that WH Smiths' Kobo was less than a rousing success.

Considering that the likes of Sony, HP and Microsoft have all struggled with the tablet market, you have to wonder what chances Tesco. Still, they have done the groundwork by buying online book and music services as well as video service Blinkbox.

As pubs close all over Britain and Dominos seems rising profits from this stay at home generation, it's clear that the supermarkets have an eye on virtual as well as physical delivery.
