1st Logo (2000 -2019)
Logo: We see the old corporate GSK logo (An orange triangle with rounded edges with the text "gsk" in it) flash in. Then, the logo beats like a heart.

Later Variants: In later years, the flash doesn't occur and the logo is already present. Sometimes, the logo does nothing at all.

Technique: Probably 2D Animation

Music/Sounds: A chorus going "Haaaaa" followed by a heartbeat. Music/Sounds Variants: On the later variant, the chorus doesn't sing. The still version has no sound.

Availability: Ultra Common. Can be seen in a lot of their commercials. Like Stanley Steemer, you can find it on big syndication networks.

Logo (2022)
Logo: We see the modern GSK logo (the text GSK but with some cuts in it) twirl around.

Variants: At the start of the video, the classic GSK shifts into the modern GSK, making the triangle drop a square-like figure.

Technique: 2D Animation

Music/Sounds: The music in the video

Availability: Current. Seen on GSK's YouTube video announcing the rebrand. You can see it here. The logo as a GIF can be seen on GSK's website. As of now, this logo has not been in any commercial.
