History of the TLD

.bio is a generic top-level domain (gTLD) that was introduced as part of ICANN’s New gTLD Program and delegated to the DNS Root Zone in 2014. It was originally applied for in 2012 and received official support from organic agriculture organisations during its early development. The registry agreement was signed in 2014 and the extension was opened for general registration that same year. Since its launch, .bio has been adopted by a broad set of users ranging from life sciences professionals to individuals looking to create personal biography profiles online. 

Main Use and Industry Position

.bio is intended as a versatile domain extension associated with life, biology, and organic topics. It is used by scientists, researchers, biotechnology firms, organic agriculture businesses, personal profile creators, and others whose work relates to biological or life-related content. The term “bio” also resonates with biography sites and personal branding, making the TLD appealing beyond strictly scientific or organic industries. .bio positions itself as a meaningful alternative to legacy TLDs for individuals and organisations that want a specific thematic identity. 

Comparison to Other TLDs

Compared to broader generic TLDs like .com or .net, .bio offers a thematic focus tied to biology, life sciences, and personal profile presentation. Unlike geographic or industry-specific TLDs that limit eligibility, .bio is open to all registrants without restriction, similar to many other gTLDs. It contrasts with legacy extensions that lack thematic association, providing clearer signalling about a site’s purpose or content domain to users.

Pros and Cons of the TLD

Pros

• Clear thematic focus on life sciences, biology, organic industries, or personal biographies.

• Open registration without eligibility restrictions, available to individuals and organisations globally.

• Memorable and distinctive for branding in niche sectors.

Cons

• Less recognised and established compared to legacy TLDs such as .com or .org.

• Potential for lower default trust or recall among mainstream internet users. 

• Competitive or premium pricing at some registrars may be higher than basic TLD alternatives.

Registration Criteria

.bio domains are available on a first-come, first-served basis to any individual or organisation worldwide. No special documentation or industry affiliation is required, and there are no specific usage restrictions tied to the content posted on .bio domains beyond general DNS and internet governance policies.

Summary

.bio is a generic top-level domain created in 2014 to serve entities connected with biology, life sciences, organic products, and personal biographies among other uses. It is open to any registrant without restriction and offers thematic branding potential for science, organic agriculture, and personal identity web sites. Although not as widely adopted as legacy domains, .bio provides clear contextual signalling and relevance for targeted audiences.
