The part played by online journalism in this year's entries was higher than in previous years, with online content found in nearly a quarter of all journalism entries, a Pulitzer release said.
Online journalism was part of the winning entries for the public service, breaking news reporting, investigative reporting, local reporting, national reporting, breaking news photography and feature photography prizes.
The awards were opened up to online-only projects for the first time this year and of 1,028 entries 65 came from 37 different online-only entities, the release confirmed.
But Politico was the only such venture to be named as a finalist and was beaten to the prize for editorial cartooning by Steve Breen of the San Diego Union-Tribune.
Elsewhere the New York Times dominated this year's prizes taking five of the journalism awards.
The Times scooped the accolades for breaking news reporting and international reporting, while the investigative reporting, criticism and feature photography awards went to individual journalists David Barstow, Holland Cotter and Damon Winter respectively.
