.cs was for several years thecountry code top-level domain (ccTLD) forCzechoslovakia. However, thecountry split into theCzech Republic andSlovakia in 1993, and the two new countries were soon assigned their own ccTLDs:.cz and.sk respectively. The use of .cs was gradually phased out, and the ccTLD was deleted some time around January 1995.

.cs domain first appeared inInternet Assigned Numbers Authority tables in autumn 1990 and in June 1991 inRIPE list. In October 1991 first domain was registered (iac.cs - Institute of Applied Cybernetics in Bratislava), in February 1992 firsthosts existed. As of December 1992 40 domains were registered, while maximum number of 114 registered domains was reached in November 1993 and February 1994.[1]

Until the deletion of.yu in 2010, .cs was the most heavily usedtop-level domain ever to be deleted. Statistics from theRIPE Network Coordination Centre show that even in June 1994, after much of the conversion to .cz and .sk had been done, .cs still had over 2,300hosts. By comparison, other deleted TLDs (.nato and.zr) may never have reached 10 hosts.[citation needed]

In July 2003, CS became theISO 3166-1 code forSerbia and Montenegro (Srbija iCrna Gora inSerbian), and remained so until 2006, when the country split and the codes for domains.rs and.me were created. However, Serbia and Montenegro did not use .cs as its ccTLD, but continued instead to use theYugoslavian ccTLD.yu until it finally expired on 30 March 2010.[2]
