(Add a horizontal line above the 'E'.) This was used, along with URNOTE, as part of a very edgy ad campaign for the original Sony PlayStation. Its brief appearances in television commercials, along with mentions in print advertising and elsewhere, led to a lot of speculation as to the meaning. When you read the first four letters backwards, pronouncing the 'E' as a long E (hence the bar) it read as "Sony." Another embedded reference: the "NOS" stood for "Ninth of September," a reference to the release date of the PlayStation.
I remember when people all over Usenet were trying to find obscure historical references to "Enos" in order to more properly explain this slogan. AFAIK, all those people needed to either get out more or play more video games.
