988. A television company that really needs no introduction–Desilu was late 60s television (Mission: Impossible, Mannix, Star Trek:TOS–need I go on?)
This is the famous "merging circles" logo, hosted at youtube.com at the account of mcy919, to whom we give thanks.
To me, this was 60s logo design at some of its best. The merging circles are symmetrical and gracefully combined, Color TV was still new at the time and any, even subtle, nod to color production amounted to a competitive advantage in the mind of the public. Once merged, the circle becomes the jot over the "i" in a graceful sweep as the script "Desilu" finshes drawing by an unseen hand, and it's all tied together by a meaty yet fleet five-note fanfare.
Mind you, this was years before "Sit, Ubu, Sit. Good dog (bark!)" and the advent of the production company ID card as micro-productions unto themselves.
The Desilu fanfare was punchy and good-sounding enough that Paramount Television, the successor to Desilu, used it for several years after.
While more-than-somewhat ineffable, the feelings I get watching the logo come together more than amply explain why, in certain ways, we keep touching back to the 60s and 70s in television culture. Sure, those decades included mounds of steaming dreck–when it was bad, it was horrid. But when it was good, it was very good–even elegant.
They don't make 'em like that anymore.
