What would happen?
We've got an alternate timeline at our disposal and all we get is Giggle? The only difference I can see is that giggle is a real word. So maybe when you clicked on the site there would be a Pillsbury Doughboy like 'hoo-hoo' or something. Other than that, what bearing does the word have on the success? I see none. That's like saying, what would the world would have been like if it had been called the Network instead of the Internet? People would never talk about the movie Network on purpose. That would be the only difference. Oh wait, that's not a difference. The only reason people or our generation even know about the movie Network is because Heath Ledge won a posthumous Oscar for The Dark Knight, and the last time that happened was the guy from Network.
Do you think the world would be a happier, funnier place because a giant conglomeration owns a jolly word? More likely you'd have to pay a fucking royalty every time you were tickled.
Short Answer: You know what would be different in an alternate timeline? I would have a job.
