Two Logitech Webcams were among Amazon's 100 best selling electronics' items on Friday, according to Amazon spokeswoman Stephanie Mantello. On Monday, a week after "Breakup" first appeared on YouTube, two more of the company's cameras broke into the top 100, including the Quickcam Pro 5000.

The Quickcam Fusion, which sells for $85.49 on Amazon, was ranked No. 95 on Friday but by Monday had jumped to No. 38. The Quickcam Pro 5000 hit No. 97 on Monday afternoon and within hours rose to No. 67.

"Maybe we don't have to do any more advertising," joked Nancy Morrison, Logitech's director of corporate communications.

Morrison said both the Quickcam Pro 5000 ($69.99 at Amazon) and the Fusion are equipped with Logitech's Visual Effects software, which allows a user to choose from dozens of avatars, or animated images, to alter their on-screen appearances. "Breakup" fans who posted comments to Bowiechick's videos clamored for more information about the effects.

It's unclear how much of an effect "Breakup" had on sales, however. Amazon said that discounts and promotions are constantly going on at the site, which could have fueled sales.

Morrison said that the company hasn't seen any conclusive proof that "Breakup" has led to a run on Logitech Web cams.

Nonetheless, after reviewing "Breakup" and another video, where Bowiechick demonstrated Logitech's avatar effects, Morrison, said the company would like to know more about the budding filmmaker. Morrison also denied rumors spreading on YouTube that the company put Bowiechick up to producing the videos.

"We've had no contact with her," Morrison said. "We would love to speak with her to learn more about how she's using the camera. But only if she wants to talk to us. We're not looking to exploit her."
