The Pulitzer Prize, considered journalism's most coveted award, is celebrating its centennial anniversary.
There were only four journalism categories when the first Pulitzers were awarded in 1917. Last year's 14 journalism categories received almost 1,200 submissions, according to Editor & Publisher.
Named after Joseph Pulitzer, owner of the New York World and St. Louis Post-Dispatch, the prizes are administered by Columbia University.
To mark the centennial, the organization has partnered with individuals and groups to host events across the country. The Poynter Institute, which owns the Tampa Bay Times, hosted one such event on March 31. TheTimes has received 10 Pulitzer Prizes over the years.
The event was called "The Voices of Social Justice and Equality" and it highlighted the achievements of journalists and others who have produced Pulitzer Prize-winning work in the service of civil rights, social equality and democracy. U.S. Rep. John Lewis, a legendary civil rights leader and an organizer of the Selma Bridge March in 1965, was the keynote speaker.
Also at the event, a short film celebrating the Pulitzer Prize centennial made its debut. You can watch it here:
