I recently heard an interview with a designer who has some level of claim to the original "Larry the Bird," Twitter's ubiquitous (and now former) logo. He made a very gracious case for the necessity of rebrands. And what else could he do? Any other response would have come off as sour grapes. He was right about the necessity of rebranding in general, but I honestly can't wrap my head around this one.
I can't count how many times a client has asked mixtape marketing to help them develop a name for their company name that will become a verb. Candidly, it's almost annoying. And just between you, me, and the rest of the internet, the reason it's annoying is because it's a really great idea to aspire to. But also because it's incredibly difficult to pull off. I'll leave it to the English majors to provide a concise explanation of how words become both nouns and verbs at the same time. Suffice to say that it doesn't work with most words, and trademarks on anything besides nonsense words are getting a lot harder to come by—but that's a whole different rant.
The best example might be "Uber." I can take an Uber (noun). Or we can Uber somewhere (verb). Better yet, these days people tell you to Uber somewhere when all they really mean is "don't bring your own car." It's like when someone asks for a Kleenex™ when they mean a tissue. In the marketing world, that's the brass ring. It just doesn't get any better. Sorry-not-sorry, Cottonelle. Nice try, Lyft.
Why, then, would anyone want to change "Twitter" to "X"? Twitter was synonymous with social media itself, and widely regarded as the world's largest and most (small "d") democratic resource for free speech—criticisms of more recent examples of censorship notwithstanding. A "tweet" (noun) and "to tweet" (verb) have literally made their way into the dictionary. In fact, dictionary.com has more definitions about Twitter and social media than the original meaning of the word "tweet." That's astounding. On the other hand, X is a symbol of censorship, caution, and anonymity. X has a thousand meanings—and maybe that's the point? But I still can't imagine anyone talking about an "x" they read. And, while I'm not an attorney, I can't see any way that "X" could possibly be trademarked.
R.I.P., Larry the Bird. We really, really knew ye.
