"AS" or "A/S" is a suffix indicating a joint stock company in some countries including Norway, Denmark and Czech Republic, so this TLD gets some use by companies of this sort.

Ås was established as a municipality January 1, 1838 (see formannskapsdistrikt).

The municipality covers 103 km², and has 14,472 inhabitants as of January 1, 2005. The center of Ås has 7976 inhabitants [1]. Ås is best known for the Norwegian University of Life Sciences (UMB, formerly Agricultural University of Norway, NLH) and the Tusenfryd amusement park, though lesser recognised attractions as the DaVinci bridge are – unfortunately – often well kept secrets for tourists and unfamiliars. Ås has also raised widely known people as Vibeke Løkkeberg, Solveig Kringlebotn, Christian Magnus Falsen, Simen Agdestein and Knut Hjeltnes, among many others. Through Ås runs both European route E6 and European route E18 (the two largest highways of Norway), and many of the inhabitants commute to Oslo, the capital of Norway.
