THE world's largest package delivery firm has completed the biggest corporate rebrand in history.

UPS, instantly recognisable through its traditional brown livery, has redesigned the shield logo which stood as a defining image of the company for 40 years.

During the course of a year, UPS claims to touch the doorstep of 98 per cent of the homes in America and reaches customers in more than 200 countries.

Eighty per cent of the world's population can be reached by UPS in 48 hours or less, the company said.

The logo appears on more than 88,000 vehicles, 257 large jet aircraft, 1,700 facilities around the world, 70,000 drop-off and retail access points, more than 1m uniform pieces and more than 3bn packages annually.
