Sellotape

Invented in West London by Colin Kininmonth and George Gray in 1937, Sellotape was both the widest and thickest tape on the market and became widely adopted as a means to seal ammunition boxes and help protect windowpanes from potential bomb damage during the British war effort.  Throughout the decades since, they've diversified their range to include a wide variety of products for every occasion.  Re-launched in 2010 by Henkel, Sellotape remain the nation's favourite tape brand by far and even have their own entry in the Oxford English Dictionary.
