Techmeme's original design (2006-2011)
Gabe Rivera launched his excellent news aggregator site called Tech Memeorandum in 2005. In 2006, it was renamed to Techmeme. We couldn't find any images from 2005, but it is well documented starting in 2006.
Techmeme redesign (2012-present)
A cleaner look and more prominent sponsor branding launched in 2012. The logo was modified slightly and dropped the italics. A mobile and mini version launched too.
