Juglans regia flavour. The Latin name for the walnut was "nux Gallica", "Gallic nut"; the Gaulish region of Galatia in Anatolia lies in highlands at the western end of the tree's presumed natural distribution. For the etymology and meaning of the word in English and other Germanic languages, see "walnut". "Walnut" does not distinguish the tree from other species of "Juglans". Other names include common walnut in Britain; Persian walnut in South Africa and Australia; and English walnut in North America and Great Britain, New Zealand, and Australia, the latter name possibly because English sailors were prominent in "Juglans regia" nut distribution
Two-sided market that the greater the multihoming costs, the greater is the tendency toward market concentration. Higher multihoming costs reduce user willingness to maintain affiliation with competing networks providing similar services. Attracted by the prospects of large margins, platforms can try to compete to be the winner-take-all in two-sided markets with strong network effects. That means that one platform serves the mature networked market. Examples of the standards battles include VHS vs Betamax, Microsoft vs Netscape and the DVD market. Not all two-sided markets with strong positive network effects are optimially supplied by a single platform. Markets must have high multi-homing costs
