I think there are a few versions of that commercial on the air. I've seen both which you're talking about at various times. So I think they do it just to have slight variations in the commercial.
Anyone seen this commercial? They talk about how many people are doing different things. Like watching videos or breaking up. Just noticed they changed it.
They had said X amount of peopled just twitted on twitter and X amount dont know what twitter is.
Now they say X amount of people just found each other on "loopt" and X amount just found they were in the same location.
Find it odd that they removed twitter from the commercial, why do you think they would pull that? Cant see Twitter complaining as it was free promotion.
