Ogilvy ditches founder’s signature as part of ‘re-founding’
David Ogilvy’s signature has been dumped as the agency’s logo in a global rebrand of the 70 year old agency he founded.
Ogilvy’s signature was adopted as the agency’s logo in 1999, a month after the legendary adman passed away at the age of 88 and a year after the company’s 50th anniversary.

The new and old Ogilvy logos
It’s also interesting to note that Ogilvy have also backed out of all production by disbanding ‘H&O’ and partnering with Hogarth as part of WPP’s apparent focus on horizontality.
Just like the JWT re-brand fiasco, this will also fail.
The logo isn’t the problems – it’s what the logo means that requires
the re-think.
This is a very kiddish way to reinvent an agency which all the big clients are looking for.
Time is the new currency.
