Dot-Com Domain Turns 30 and Is Still Growing

After 30 years, the dot-com (.com) top-level domain (TLD) continues to dominate the Internet, but now faces more challengers than ever.

There has been a dramatic expansion in the availability of TLDs in the past few years. In 2011, there were only 22 TLDs from which to choose. In June 2011, ICANN approved a proposal to overhaul the TLD system, enabling a new era of generic TLDs (gTLDs).
