Dan Borislow, whose "MagicJack," peddled in television infomercials, helped pioneer free phone calls through the Internet, has died. He was 52.
Borislow died Monday of a heart attack after playing in a soccer game in West Palm Beach, Fla. His death was confirmed by Brad Shewmake, a spokesman for MagicJack Vocaltec Ltd., the maker of the device. Borislow was the founder and former chief executive of the company, based in Netanya, Israel, and West Palm Beach.
The company has sold more than 10 million MagicJack units, which connect to a computer's USB port or router to enable voice calls over the Internet. More than 25,000 retail stores sell the device.
