NBC will begin broadcasting its entire late-night lineup in HDTV next year.

The network was the first to broadcast a nightly series in HDTV when it began HD production of "The Tonight Show with Jay Leno" in 1999.

Additionally, two of the network's annual signature holiday specials, "The Macy's Fourth of July Fireworks Spectacular" and "The Macy's Thanksgiving Day Parade" will also be broadcast in HD beginning in 2005.

The late-night conversion is scheduled to begin in April 2005 when NBC's "Late Night with Conan O'Brien" converts to HDTV. "Saturday Night Live" will convert to HD with the fall 2005-06 season premiere, as will "Last Call with Carson Daly," which shares "SNL's" studio.

Currently, NBC broadcasts 90 percent of its scripted entertainment programming in high definition.

As of Dec. 1, NBC Universal Cable Group also launched Universal HD, which is currently available to more than 25 million homes. Universal HD offers the best of NBC Universal's library in HD.
