Also, because they can be a good way to kill a couple minutes of boredom. (B) At this point, Spider-Man's presence in the trailer has, at most, only raised interest in the trailer. Whether it raised interest in the movie itself (and by how much) remains unknown, because we don't know how many of the people who watched the trailer were impressed enough by it to decide to see the movie (when they were previously not considering it). It's seems likely that at least some of the people who watched the trailer thought"eh, big deal" and walked away having no interest in seeing the movie. The argument that Spider-Man's presence has raised ticket sales remains an invalid one, simply because the only "evidence" being offered in support of it is youtube trailer hits, which has nothing whatsoever to do with ticket sales.
Is it possible, even likely that Spider-Man could help ticket sales? Sure. But to definitively declare that he already has helped ticket sales based solely on trailer views is wildly speculative and premature.
