Free Skype? Nothing lasts forever.

Skype, the internet telephony service made by the guys who made file sharing popular in the late 90’s, has been free since May allowing millions to make long distance phone calls for free, now that’s all changing. Starting the first of the year eBay, the current holders of the corporate strings, will start charging to use Skype.

eWeek: eBay Inc.’s Skype, which competes with traditional phone companies and Web operators like Vonage Holdings Corp. for customers, said subscribers who sign up for the plan before January 31 will get the service for half price.

The service covers calls to mobile phones or traditional wire line phones from computers or from a new category of Internet-connected phones that run Skype software.
