C-lehti was started in 1987[1][2] as a spin-off of MikroBitti and was published six times per year.

Originally, it covered the Commodore 64 (and to a lesser extent, its "bigger brother" Commodore 128) and the Amiga computers, but later it became more and more Amiga-centric, as the 64 and 128 were rapidly becoming obsolete.

[4] Later, as the Amiga started to lose market share to the PC computers and games consoles, C-lehti discontinued and Pelit was established in 1992 as its successor which concentrated on PC and Amiga gaming.

A character in C-lehti was the Guru, drawn by Harri "Wallu" Vaalio.

The Guru, a bald man with a bushy beard and a shiny scalp, was the symbol for the magazine's hints and tips column.
