Internet telephony provider Skype announced Friday it now has more than 100 million registered users worldwide. Luxembourg-based Skype had 54 million members when it was bought last September for $2.6 billion by online auctioneer eBay. Founded by the creators of Kazaa, the free file-sharing program that riled the music business, Skype gives away software that lets people talk for free from computer to computer, or pay a small fee to place and receive calls from regular phones.
