What is Uber has been a question probably asked by many in recent years.
Well now, in the latest twist in the private firm's chequered history, an EU court has ruled it's a taxi company rather than a tech firm.
That means it can now be regulated as a transport firm, meaning its rules can be set country-by-country.
Meanwhile, rules for digital platforms from tech firms are set Europe-wide.
The EU ruling comes on the same day Uber returns to court to outline an appeal against its London licence being refused to be renewed three months ago by Transport for London.
TfL said Uber was "not fit and proper" to hold a London licence.

An Uber spokesperson was quoted as saying today: "This ruling will not change things in most EU countries where we already operate under transportation law…
"It is appropriate to regulate services such as Uber and so we will continue the dialogue with cities across Europe."
