Great Universal, Kays and Empire Stores were all part of the Shop Direct Group. Their trading operations have now been merged to become K & Co. That company mainly trades online but you can still order a catalogue from here:

Index wasn't strictly a 'home shopping' catalogue (in the way that others referred to above were). It was Littlewood's failed attempt to mimic Argos. (i.e. you ordered in a store, without the credit facilities offered by 'proper' home shopping catalogues).
I may be wrong Chris - but I thought Littlewoods stores on the High Street and Littlewoods catalogues were completely different concerns (I used to be a Littlewoods agent for the catalogue)
The Fattorini family were the pioneers of home shopping....my Mum used to run one of their catalogues and had lots of customers, fraught with problems at times.

Littlewood's catologues (and John Moore's catalogues), Liitlewood's stores and even Littlewood's football pools were all part of the same business:
