For those who think that running a TLD is a licence to print money, the experiences of gTLDs introduced since 2000 suggest otherwise. In the past 10 years, .comโs market share may have declined from approximately 50% in 2001 to 44% in 201013, but in real terms .com registrations have nearly quadrupled. In contrast, the domain intended to offer direct competition (.biz) has stayed level at around 2% of market share. The most successful of the new gTLDs, .info, with 7m domains after 10 years of operation, has only just overtaken its original โmoderateโ projections for 5 years.
According to ICANN economic analysis, .mobiโs relevance had declined with advances in device aware web-technologies, and this may have contributed to a low renewal rate (37%) . The study warned that โfailure to take potential alternatives into account can result in a significant over-estimate of the likely benefits of a gTLDโ. Even for restricted domains, such as .museum, the study found that only 1.4% of eligible registrants (ie museums) had registered in the domain. Similarly, low registration figures in .aero indicate that โairports have not perceived significant benefits from the gTLDโ.
