Founded as the Electric Telegraph Company in 1846, BT has a pretty colourful history. The company went through various iterations after it was brought under the General Post Office government department in 1912 and was finally privatised in 1984, officially becoming British Telecommunications.

Today, BT is still best known for its telecoms business but it has built up a sprawling empire over the years, encompassing mobile, cyber security, healthcare and sports broadcasting, among other things. The company’s array of sub-brands had become equally sprawling as a result, including hundreds of different logo artworks, roughly 15 brand colours and many different sets of design guidelines.
