3K

3K, short for , was the youth-oriented, third main television channel of Radio Television of Serbia.
==Festovizija==
===January–February 1989===
Frequencies of what would later become Omladinski kanal - and later 3K - were initially used for a temporary television service operated during the FEST film festival in Belgrade, named Festovizija, during which reports and films were broadcast from 9am to midnight. This channel broadcast for ten days from January 26 to February 4, 1989. After Festovizija closed down, another temporary, seven-day (February 5 to 11, 1989) service followed - broadcasting in parallel to the then-ongoing YU Video Show being held, with programming, in similar vain, also being dedicated to the event.

On May 22, 1989, broadcasts resumed under the Omladinski Kanal name, only to be shut down merely a month later, on June 30, 1989; the following day, 3K was finally launched.
==3K (first era)==
===1989–1990===
3K did not have a logo until 1990. Various variants of the name were seen on idents and intros.
===1990–1996, 2000–2001, 2003===
Perhaps the best-known logo of the channel, it was originally used from 1990 to around 1996, and then reused from after October 2000 until 2001, when the blue brick logo was adopted, and again for around a month in late 2003 (around October to November), after which the last logo was introduced. After 1993 the on-screen bug became the white RTS logo without any embellishments, only to be supplemented with this logo the following year.
===1990, 1992–1993===
The logo had the text "3K" on the top, and the text "TVB" spaced on the bottom, representing the third channel of Radio Television Belgrade. Used as an on-screen bug.
==RTS 3 (first era)==
===1995–1996===
Between late 1995 (around the date where RTS logos became uniform) and January 1996, this logo was used, matching the style of RTS 1 and RTS 2.
==3K (second era)==
===1996–2000===
This logo was only used as an on-screen bug.
===1997–2000===
This logo was used mostly for idents and intros and was not displayed as an on-screen graphic.
==RTS 3 (second era)==
===2001–2003===

In December 2001, 3K became RTS 3 and changed its logo to match the other two channels, for the second time. After this name was retired, it would not be revived until 8 June 2015 which is when a completely unrelated RTS 3 launched, replacing RTS Digital.
==3K (third era)==
===2003–2006===
Due to issues with RTS and a planned sale, the channel was divested by the broadcaster (along with erstwhile Radio 101) and reverted back to its original name in October 2003, yet this logo was introduced the following month. A year later, in October 2004, these two services were reintegrated into RTS, as no sale ever occurred.
A new broadcasting law prompted 3K to stop broadcasting a year and a half later, on May 5, 2006. Until the launch of TV Avala on September 17 that year, a temporary feed of RTS 1 fulfilled the signal previously used by 3K.
