New TLDs (top level domains) continue to become live. There are hundreds to choose from. Gone is the day that there were only a handful, and a business could tie them all up for their corporate name and brands.
Also gone is the day that they are all inexpensive. Some of the new TLDs command a premium price. A .lawyer TLD, for example, costs US$6500. A .guru domain is a bargain at US$29.
