In the 1980s, the idea of cord cutting was nothing more than a pipe dream as we watched analog cable and stared at the monochrome green CRTs on our computers. However, we did have portable, battery-powered TVs that picked up over-the-air broadcasts much like a radio. Who could forget the Sony Watchman?
Though most smartphone users watch video on demand from services like Netflix and Hulu+, there are plenty of ways to get live TV on your handset. If you own an iPhone, Elgato Systems' $82 EyeTV Mobile is a digital antenna that plugs directly into your handset and picks up over-the-air broadcasts. Audiovox's $130 Mobile TV box connects to your Android or iPhone via Wi-Fi, but gets all its content via antenna.
You can watch live cable TV from your phone by connecting a Slingbox to your cable box at home and viewing it over the Internet. Several cable companies also provide online services such as Aereo, Sprint TV and T-Mobile TV, which offer a few live channels for a monthly fee.
