Steeped in a data-use controversy that will likely shape how personal data is used and gathered in the future, political consulting firm Cambridge Analytica announced that it will be closing its doors.

Based in the U.K., Cambridge Analytica has been accused of working on behalf of some of its political clients, culling the data of roughly 87 million Facebook users to influence the outcomes of both the 2016 U.S. presidential election as well as the U.K. Brexit referendum.

Accusing the firm of "improperly" gathering data using a quiz app, Facebook vows to continue its investigation into the data harvesting, despite the announced closing.

"This doesn't change our commitment and determination to understand exactly what happened and make sure it doesn't happen again," said a Facebook spokesperson.

"We are continuing with our investigation in cooperation with the relevant authorities."

Appearing on the beleaguered company's site is a statement announcing the news and a simultaneous denial of any wrongdoing:

"Over the past several months, Cambridge Analytica has been the subject of numerous unfounded accusations and, despite the company's efforts to correct the record, has been vilified for activities that are not only legal, but also widely accepted as a standard component of online advertising in both the political and commercial arenas," it said.

"Despite Cambridge Analytica's unwavering confidence that its employees have acted ethically and lawfully... the siege of media coverage has driven away virtually all of the company's customers and suppliers. As a result, it has been determined that it is no longer viable to continue operating the business."
