Ernst & Young officially change their name to just "EY" some years back.

Unfortunately, they forgot to check the name beforehand, and it turned out that "EY!" already existed: a gay porn magazine.

Yes, this really happened.

They changed their name to from Ernst & Young to EY in 2013.

Not by me, but by the mods. They also changed from "full of hallucinations" to "and most citations were hallucinated". Maybe a rep from "EY Global" filed a complain ;)
