The magazine published a 186-page centenary special in April 2013, the largest single issue in its history. It also published two special editions (250 and 150 pages), showcasing 100 years of the best and boldest journalism from its archives. In the following year it expanded its web presence by establishing two new websites: May2015.com, a polling data site focused on the 2015 general election, and CityMetric, a cities magazine site under the tagline, "Urbanism for the social media age" and edited by Jonn Elledge.
