c't (short for "Computertechnik") is a German biweekly computer magazine, published by the Heise Verlag publishing house.
The first issue was published in December 1983.
c't had a sold circulation of ca. 385,000 in the second quarter of 2002.
The magazine has a reputation of being very thorough, although some critics claim that the magazine has been "dumbed down" in recent years to accommodate the mass market.
c't covers both hardware and software; it focuses on software for the Microsoft Windows platform, but Linux and Apple Computer are also regularly featured.
It has a sister magazine iX, which focuses primarily on UNIX-related issues.
