CAN THEY DO THAT? Millennials Unearth an Amazing Hack to Get Free TV: the Antenna.

“I was just kind of surprised that this is technology that exists,” says Mr. Sisco, 28 years old. “It’s been awesome. It doesn’t log out and it doesn’t skip.”

Let’s hear a round of applause for TV antennas, often called “rabbit ears,” a technology invented roughly seven decades ago, long before there was even a cord to be cut, which had been consigned to the technology trash can along with cassette tapes and VCRs.

The antenna is mounting a quiet comeback, propelled by a generation that never knew life before cable television, and who primarily watch Netflix , Hulu and HBO via the internet. Antenna sales in the U.S. are projected to rise 7% in 2017 to nearly 8 million units, according to the Consumer Technology Association, a trade group.

Mr. Sisco, an M.B.A. student in Provo, Utah, made his discovery after inviting friends over to watch the Super Bowl in 2014. The online stream he found to watch the game didn’t have regular commercials—disappointing half of his guests who were only interested in the ads.

“An antenna was not even on my radar,” he says. He went online and discovered he could buy one for $20 and watch major networks like ABC, NBC, Fox and CBS free.
