The progressive site ThinkProgress shut down on Friday in yet another sign of how much the news media landscape has changed in the past decade.

The development was not much of a surprise to current or former employees. In July, the Center for American Progress, the progressive think tank behind the editorial venture, put the site up for sale.

In a statement on Friday, the think tank blamed the lack of a buyer on its decision to close the site. The shutdown, which led to the layoffs of a dozen remaining staff members, was first reported by The Daily Beast.

“We are very sad to announce that after more than two months of searching, we have been unable to identify a new publisher for ThinkProgress, and we are left with no choice but to close ThinkProgress as an independent enterprise focused on original reporting,” the statement said.
