Carly Rae Jepsen's "Call Me Maybe" has held the number one spot on the Billboard Hot 100 for 9 weeks now, the longest run in that spot for 2012 so far. There are thousands of parodies and sing-alongs to the song on YouTube. It's near impossible to avoid the song on any pop-friendly radio station.

So here's a question: what is CallMeMaybe.com worth?

A lot, hopes Preston Hershorn, a 24-year-old who works in marketing at Google. In late February, he heard the song at a friend's house and decided, as he put it, "This is a hit."

One day later, Justin Bieber, Selena Gomez, and Ashley Tisdale posted a YouTube video of themselves lip-syncing to the song, pushing "Call Me Maybe" into official viral territory. After that, Hershorn and some friends, goofing around while watching the Oscars, filmed a parody lip-sync video of their own. Looking for somewhere to host it, Hershorn bought CallMeMaybe.com for well under $500 (he wouldn't give an exact figure), simply as a place to host the clip.

"I'm a marketer after all. I love a strong vanity URL," Hershorn says. For nearly six months, CallMeMaybe.com has hosted the homemade video produced by him and his friends, and nothing more.

But as the song continued to top charts throughout the summer months, Hershorn found he didn't have much use for the domain anymore, and hoped he might sell it. This week, he listed the site for a starting bid of $1000 on eBay.
