Puls 4 Austria was launched on June 21, 2004 as Puls TV Austria. Its first logo consists of six orange balls who are enlarged a bitter with the sixth orange ball is too small. Below the six orange balls appears the word "Puls TV" in matrix typeface.
On January 28, 2008, Puls TV Austria was renamed to Puls 4 Austria and replaced the six orange balls by a rounded-square in pink colour which carries the matrixed number four inside. Beside it, appears the world "PULS" not more longer cursive but instead normal. Note that the L is connected into the S.
In December 2015, Puls 4 Austria introduced a new logo which removes away the word "PULS" and remains only the symbol which is the number 4 in a pink square. This is the final set of idents to be aired before the station got its current logo and besides, this logo is short-lived for 10 months.
In 2016, the number 4 logo was changed to look like the logo of British broadcaster Channel 5 and the logos of some American television stations that broadcast on channel 4, except that the logo is italicized and split into two unequal segments.
