The analogue cervicography, which was developed at the University of Wisconsin, was first adopted domestically by NTL. Since then, NTL has made efforts in order to drop the incidence rate of cervical cancer, and thus, it has succeeded as the rate dropped from first to seventh place in Korea. In 2012, the world's first wireless cervicography was developed by NTL. In addition to being an importer or manufacturer, NTL is also a sales & marketing company with experience in new product marketing. NTL holds a very strong sales network and has continuous in-service contracts with more than 1,000 clinics and hospitals in Korea.
