The Texas Observer, the storied progressive publication known for its feisty, combative and often humorous investigative journalism, is shutting down and will lay off its 17-person staff, including 13 journalists, several members of its board said Sunday.

The decision marks an end to 68 years of publication, starting with its founding in 1954 by Ronnie Dugger and including a six-year period under the helm of the legendary Molly Ivins from 1970 to 1976. The magazine, in its first few decades, represented the liberal wing of the once-conservative Democratic Party. It was a thorn in the side of Lyndon B. Johnson when he was Senate majority leader (before he became president), Govs. Allen Shivers and John B. Connally, and other conservative Democrats. And it chronicled the era in which Texas was remade into a Republican stronghold that sent a governor, George W. Bush, to the White House.

The closing of the Observer raises questions about whether small progressive publications can survive the digital transformation of journalism and the information ecosystem during a time of rapid social, demographic and technological change.
