The Web Trend Map is a yearly publication by iA Inc. It maps the 333 most influential Web domains and the 111 most influential internet people onto the Tokyo Metro map. Domains are carefully selected by the iA research team through dialogue with map enthusiasts. Each domain is evaluated based on traffic, revenue, age and the company that owns it. The iA design team assigns these selected domains to individual stations on the Tokyo Metro map in ways that complement the characters of each.
