The acquisition, which closed March 1, includes the rights to all exclusive intellectual property, as well as MovieBox, a video-on-demand membership site, and dating site Sex in Your City.
"The company is run by industry veterans who also operate multiple other brands in the adult entertainment industry," Manwin said in a release.
Manwin said it has taken over all aspects of operations but has retained previous staff.
Manwin also said the acquisition allows it to further develop branded adult websites, while its tube sites begin operating with new initiatives, such as the company-developed Paid Content Partner Program that provides text links to boost traffic for content owners.
In a statement, Manwin said that the company's new tube site initiative will be "conducted with the belief that there is a place for tube sites in our industry and a way to utilize them to serve Manwin’s business interests, as well as those of its partners."
"Other tube site owners are encouraged to do the same to aid the adult industry, instead of simply aiming to make content freely available to all," the company said.
