Logo
In 1969 Michael Jeans-Jakobsson, then Station Director came up with the initials YSTV for the newly formed student television station, and they have remained in use ever since. The realisation of those letters into a visual logo has varied considerably over the years since then. Unfortunately the original logo has not survivedUnverified or incomplete information, but is described as similar to the current (2000) logo.
Not much is known about other early YSTV logos, however Election 84 does feature a rather intimidating logo featuring a rather Orwellian-looking Eye of Ra.
This logo (left) also appears in photos from the mid-80's. (It's got some stuff in the way, the actual logo doesn't have the vertical black lines), and on some paperwork from the period.
In 1986 the launch of colour broadcasting saw the introduction of a new colour logo, but it didn't last very long, by 1989 the cube logo was in use. The text and rendering of the logo changed over time - a stylised version was in use in the mid 90s, while a capitalised version was in use by the time it was scrapped.
By 2000 this was thought to look dated, and so the current YSTV logo was designed by Matt Hammond and launched in the summer of 2000. This has remained in use ever since, although frequently extended, for example in the Idiot Logo.
