Logitech and Creative, which together own about three-quarters of the Webcam market, joined Skype on Thursday to co-market the Luxembourg-based VoIP developer's newest software with their cameras and headsets.

On Thursday, Skype released the beta version of Skype 2.0, which features integrated video calling.

Skype worked with Logitech and Creative to ensure that their webcams would work properly with the new video function of Skype 2.0, company officials said.

Many of Logitech's QuickCam line of webcams have been certified to work with Skype 2.0, including the Fusion, Orbit, Pro, Zoom, and Notebooks Pro models. Creative, meanwhile, has introduced the Creative WebCam Instant Skype Edition, which bundles a webcam with headset, Skype, and a stand-alone microphone.

Creative's Skype-certified webcams will be available at retailers in Europe, while Logitech's can be purchased through the Skype online store. Skype 2.0, which requires Windows 2000 or Windows XP, can be downloaded from the Skype Web site.
