Get an over-the-air antenna
All TVs since 2007 have been required to include a digital TV tuner. That means you can get free over-the-air local broadcasts—including ABC, CBS, NBC, and Fox—simply by connecting an antenna to your TV’s antenna input.
But your reception will depend on your distance from a broadcast tower, the terrain, and the surroundings (nearby houses, buildings, trees, and so on). We recently had a dozen employees test 10 different antennas in the NY metropolitan area, and eight were able to get at least some reception. And you don't have to pay very much: The least expensive antenna we tested cost about $10, and one of the best-performing models cost only $35.
Try out Aereo
For those, like me, who aren’t able to get decent reception using an over-the-air antenna, Aereo is another somewhat ingenious option. Although it’s not free, for about $8 a month Aereo connects you to your own tiny microantenna housed in its facilities, delivering over-the-air TV signals to you via the Internet.
Right now Aereo is only available in a few markets, but New York is one of them. The monthly fee includes 20 hours of free cloud DVR storage, which jumps to 60 hours if you’re willing to pay $12 per month.
Become an Amazon Prime subscriber
Talk about great timing. Before the start of the summer TV season, Amazon signed an exclusive licensing deal with CBS to let Amazon Prime subscribers watch new streaming episodes of "Under the Dome" just four days after they air on TV.
Amazon Prime Video is a free benefit to Amazon Prime subscribers, who pay $79 per year to get free two-day shipping. Obviously this is a solution for "Under the Dome" fans, but not necessarily other popular CBS shows, such as "The Big Bang Theory" and "NCIS."
