How do I know if I already have a digital TV (DTV)?

If your television set is labeled as “analog” or “NTSC,” and is NOT labeled as containing a digital tuner, it most likely contains an analog tuner only.

If your TV was built before 1998:  Almost every TV set made before 1998 was a traditional analog set.

Projection TVs manufactured between 1998 and 2004: Only a limited percentage of projection TV sets (and generally only those 42 inches in diameter or larger) included digital tuners before 2004.

TVs manufactured 2004 and after: Your chances of having a built-in digital tuner improve dramatically. Many of the TV sets sold at popular electronics stores feature digital tuners that will work after February 17, 2009.  Note: Some TVs manufactured from 2004 to 2006 were advertised as “HD-ready” or “HDTV monitor” sets. That means they can display digital and high-definition signals, but they need help getting those signals in the first place. You’ll still need a special converter or a cable TV connection.

TVs manufactured after March 1, 2007:  By law, all television sets manufactured for sale in the U.S. after March 1, 2007 must contain a digital tuner (NTSC tuner).  TVs labled as containing a digital or NTSC tuner do not require a converter box.
