Such has been the enormous growth in the so-called sharing economy that it's been difficult to keep up.
Luckily the folk at LoveHomeSwap have put together a rather handy interactive guide to showcase as many of the brands which have emerged in recent years into one place.
Users can just click on a country and learn more about the brands located there and what they are doing.
Perhaps one angle to ponder is how many of these brands will still be kicking about in a few years, not least if the legal difficulties some still face are ironed and the so-called big boys move in either through acquisition or having a go themselves.
