High-definition television (HDTV) in the United States was introduced in 1998 and has since become increasingly popular and dominant in the television market. Hundreds of HD channels are available in millions of homes and businesses both terrestrially and via subscription services such as satellite, cable and IPTV. In January 2013, Nielsen Media Research reported that 75% of American homes contain at least one HDTV.[1]
The Federal Communications Commission (FCC) began soliciting proposals for a new television standard for the U.S. in the late 1980s and later decided to ask companies competing to create the standard to pool their resources and work together, forming what was known as the Grand Alliance in 1993.
On July 23, 1996, WRAL-TV (the CBS affiliate in Raleigh, North Carolina) became the first television station in the United States to broadcast a digital television signal.[2]
HDTV sets became available in the U.S. in 1998 and broadcasts began around November 1998. The first public HDTV broadcast was of the launch of the space shuttle Discovery and John Glenn's return to space; that broadcast was made possible in part by Harris Corporation.[3] The first commercial broadcast of a local sporting event in HD was during Major League Baseball's Opening Day on March 31, 1998, the Texas Rangers against the Chicago White Sox from The Ballpark in Arlington in Arlington, TX. The telecast was produced by LIN productions and broadcast locally on Fort Worth, Texas NBC affiliate KXAS channel 5. This telecast was also the first commercial HD broadcast in the state of Texas.[4] The first major sporting event broadcast nation wide in HD was Super Bowl XXXIV on January 30, 2000.
Satellite television companies in the United States, such as Dish Network and DirecTV, started to carry HD programming in 2002. Satellite transmissions in the U.S. use various forms of PSK modulation. A separate tuner is required to receive HD satellite broadcasts.
Cable television companies in the U.S. generally prefer to use 256-QAM to transmit HDTV. Many of the newer HDTVs with integrated digital tuners include support for decoding 256-QAM in addition to 8VSB for OTA digital. Cable television companies started carrying HDTV in 2003. Currently, HD programming is carried by all major television networks in nearly all DMAs, including ABC, CBS, NBC, FOX, PBS, The CW, MyNetworkTV and Telemundo; and on many independent stations.
