Back in 2001, RIM apparently hired a consultancy called Lexicon Branding to find a fitting title for its wireless messaging devices. Understandably, RIM had been toying with various names that included and/or played on the word "e-mail." But after Lexicon convinced the company to consider other options—many folks subconsciously associate "e-mail" with work, and the word can, therefore, lead to raised blood pressure—someone noted that the tiny keys on RIM's older devices resembled a group of seeds.
The team then considered a variety of seeded fruits and vegetables before ultimately deciding on "BlackBerry," since RIM's devices were largely colored black at the time.
