The first true EFB, designed specifically to replace a pilot's entire kit bag, was patented by Angela Masson as the Electronic Kit Bag (EKB) in 1999.[8] In 2005, the first commercial Class 2 EFB was issued to Avionics Support Group, Inc. with its Constant Friction Mount (cfMount) as part of the EFB.[9] The installation was performed on a Miami Air Boeing B737NG.[9]
