RPC Canal 4

Background
RPC-TV is a television network, and is headquartered in Panama City, Panama, with repeaters throughout the country. The station broadcasts in NTSC format and in Panama City also in DVB-T format. Founded on late 1958, RPC is the oldest commercial TV station in Panama and Central America overall, airing imported shows, programming for kids, and local and international sporting events. It didn't use a logo until 1960.

1st Logo (1960-1968)
Visuals: The only source of this logo is that on a grey background, there's a rounded rectangle with the text "RPC" on it.

Technique: Unknown, as it's logo for now is only a capture for it's long-lost existence.

Audio: Unknown.

Availability:  We are unsure if there's a video of this logo, as their first of it's broadcasting days are for now history.

2nd Logo (1968-1980)
Visuals: On a brown background with colorful lines, there is a yellow circle, inside it is Huaca (weird creature with smile up to his eyes and wearing a weird hair design. And wearing a yellow outfit), The name of the company does not appear.

Trivia: RPC's iconic logo came from a pre-Columbian piece called Huaca.

Technique: None.

Audio: None.

Audio Variant: On startups and closedowns, they used it's national anthem (Himno Istmeño) as it's music. Sometimes it would use it's stock music, "Lamento" composed by Avelino Muñoz.

3rd Logo (1980-1984)
Visuals: On a black background, we see several shot's of a circle, which has a Huaca inside it. Then it cut's to several shots of another Huaca statue, one of the shot's have the image zooming out before cutting to the image of the previous logo but closer (so that you can see his teeth) moving. Then it fades into the same Huaca statue from earlier spinning moving to the left side of the screen before vanishing, then we see that same Huaca statue but smaller spinning around inside a springing dot forming a circle, then the "RPC" fade's in.

Technique: A lot of camera controlled animation of the images, and CGI of the spinning Huaca statue and text fading in.

Audio: A traditional Panamanian theme with a announcer.

4th Logo (1984-1988)
Visuals: On a blue background with a source depending on the Brodcasting, there is a beam drawing a abstract shape for the entire logo to fit in, then then golden words "RPC" flying into place. Then the same Huaca from before zoom's out to it's place, and then a big golden 4 zoom's out before stopping and then it turn's red.

Technique: CGI.

Audio: Depending on source, sometime there's a announcer.

5th Logo (1988-1990)
Visuals: On a sky background with a metal platform, we see some ring's forming the Olympic logo, then the same logo animates like before.

Technique: CGI.

Audio: A dance synthesizer theme with a announcer.

6th Logo (1990-1992)
Visuals: On a black background, there is a state of where RPC was started, followed by the logo flying in.

Technique: CGI.

Audio: A congo-like theme.

7th Logo (1992-1994)
Visuals: On a black background, we see red colored sphere's, then zoom's out that it's forming the Huaca from before but stylized, the company does not appear.
