Radio Philippines Network

Background
The Radio Phillipines Network was founded in 1960 by Roberto Benedicto as "Kanlaon Broadcasting System." It commenced broadcast television on October 15, 1969. When Martial Law began in the Philippines, KBS was allowed to remain on the air, unlike ABS-CBN, which was shut down by President Marcos. Its name was changed in 1975 to Radio Philippines Network. After the Martial Law ended in 1986, RPN began to decline. Today, the channel is known as CNN Philippines and the company retains the RPN name.

Logo (1960)
Logo: The letters K, B, and S in a green box. The K is on the top and is larger than the B and S, which are on the bottom. This spells out the acronym for the Kanlaon Broadcasting System.

Variants: None known.

Technique: Most likely cel animation, but could also just be a drawing. It should be noted that KBS at the time was a radio network, so, the logo could not have been seen on screen anywhere. In all likelihood, it's just a print logo.

Music/Sounds: None known.

Availability: Long extinct.

Logo (1969)
Logo: The letters K, B, and S in a blue box. The letters are positioned in a similar manner to the previous logo. The blue box is inside a square-like number 9, on a red background. The number 9 represents RPN's flagship Television station, DZKB-TV 9 Manila.

Variants: None known.

Technique: The animation is possibly a cel animation. This was the first appearance of the KBS logo on TV.

Music/Sounds: None known.

Availability: Extinct.

Logo (1975-1980)
Logo: A CBS-looking eye within a blue oval. Within the oval, there are the letters "rpn," standing for Radio Philippines Network.

Variants: Sometimes, a number 9, much like the one described in the previous logo, appears alongside the main logo.

Technique: The animation is possibly a cel animation.

Availability: Extinct.

Logo (1980-1982)
Logo: The stylized letters of RPN, and a red, green, and blue curved line. The lines contact the letters in such a way that the logo looks like a transmitter.

Logo (1982-1989)

Variants: A variant from 1987 where the RPN logo zooms out from the side, causing an explosion. A laser beam generates the RPN-9 THE LEADER logo.
