“Shouldn’t that be Think Differently?”
That would be grammatically correct, but the poster is a take-off on the famous Apple Computer poster of bygone days.
“Shouldn’t that be Think Differently?”
Yes it should but this is a throwback to Apple’s 1997 ad titled: Think Different.
“Think different.” was an advertising slogan for Apple, Inc. (then Apple Computer, Inc.) in 1997 created by the Los Angeles office of advertising agency TBWA\Chiat\Day.[1] The slogan has been widely taken as a response to IBM’s slogan “Think”.[2][3][4]
