Walmart redesigned their logo in 2008, and the shift was apparently pretty haphazard, if this report is correct. It is certainly a friendlier look. I remember when Wal-Mart stores (then hypenated) appeared in Canada, and its logo look barely less friendly than an outpost of the US Army:
The uppercase letters were monolithic, and the star was as American as... well, the US army:
The logo change in 2008 was softer.... the font was lowercase, rounder, and more "friendly". It's more "approachable", for sure. It was surely designed to embrace Walmart's (now un-hyphenated) growing global presence.
Nobody knew what the starburst was supposed to represent, but hey, it looked pretty. Like a flower, perhaps - or a flash from a far away galaxy.
Unfortunately, Walmart's global expansion has been viewed by many as a form of economic colonialism - taking over the world, one rollback at a time. This new logo was likely created in part to address this concern by appearing more friendly, and less American.
Which brings me to my point: was the designer lazy, or insidiously devious? Either way, you have to admit.... the new logo looks a hell of a lot like the logo of the Galactic Empire.
Party on, Darth.
