Norwegian Sign Language, or NSL (Norwegian Bokmål: norsk tegnspråk or Nynorsk: norsk teiknspråk, NTS), is the principal sign language in Norway.
There are many sign language organizations and some television programs broadcast in NSL in Norway.
The Norwegian Broadcasting Corporation airs Nyheter på tegnspråk (News in Sign Language) daily and Tid for tegn (Time for Signs) weekly.
Out of a sample of 96 sign pairs, 18 pairs were identical between the two languages, 26 showed some level of similarity, and 52 appeared completely unrelated.
It is not yet known to what degree the similarities are a result of direct borrowing, borrowing from a common source language (such as ASL or International Sign), mimesis of the thing they refer to, or sheer coincidence.
