ICANN is the Internet Corporation for Assigned Names and Numbers. From the BBC article:
A complete overhaul of the way in which people navigate the internet has been given the go-ahead in Paris.
The net's regulator, Icann, voted unanimously to relax the strict rules on so-called "top-level" domain names, such as .com or .uk.
The decision means that companies could turn brands into web addresses, while individuals could use their names.
Big companies with valuable brands fear they will have to spend time and money buying up every possible domain name - while reaping little gain from the liberalisation of this market.
