This question already has an answer here:
Today I was driving by a UPS truck, which for those unfamiliar is a delivery truck used by a shipping company.
By standard definition UPS could be seen as an acronym as you can pronounce it "ups" however everyone (including the company) pronounces each letter instead, much like an initialism.
So my question is, in cases like these, which is it? Does the definition of acronym merely mean that a set of letters can be easily said, or does the actual implementation of the letters change the definition? As in, if a company chooses to pronounce their name as an initialism, does it become one?
