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 the Harris Corporation. 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 overseen by LIN Productions president and Texas Rangers television executive producer Lee Spieckerman. The game was also the inaugural telecast on the digital channel of Dallas/Fort Worth, Texas NBC affiliate KXAS channel 5. The event was simultaneously shown via satellite at a reception attended by members of congress, the FCC and members of the industry in Washington, DC. This telecast was also the first commercial HD broadcast in the state of Texas. The first major sporting event broadcast nationwide in HD was Super Bowl XXXIV, broadcast by ABC on January 30, 2000. By the 2014–15 season every network show producing new episodes had transitioned to high definition.
