FX was launched on June 1, 1994 as fX with a split rectangle as its first logo. The left side had a lowercase F, and the right side had searchlights resembling the X.
In early 1997, the network's name was altered to make both letters uppercase, with yellow searchlights inside a black rectangle. The FX name is seen next to the rectangle. In a variation seen below, the rectangle is green and the searchlights are white.
In late 2007, FX altered the logo by dropping the searchlights icon from it. There's also a variation of this logo with the slogan "There is no box".
In April 2013, FX adopted the International logo (with the F and X attached to each other) and adopted the slogan "Fearless". The on-screen bug in programs is silver.
