Television Academy Hall of Fame (ABC, 8-9:30 p.m.): I'm not sure what it takes to qualify as a TV legend these days, but the seven people being inducted this year (two posthumously) have certainly achieved enough - on and off camera - to merit the salutes they're receiving. They are Bob Newhart, Phil Donahue, John Chancellor, Dick Clark, and three names not quite so widely known: TV producer Mark Goodson, whose quiz and game shows helped shape TV for three decades; Agnes Nixon, writer-creator of daytime serials like ``All My Children''; and Jack Webb, star, producer, and director of ``Dragnet.''
Milton Berle, the first to be inducted in the Hall of Fame (in 1984), helps present the honors.
Investigative Reports (A&E, 9-10 p.m.): ``HUD: America's Slumlord'' throws a harsh light on the Department of Housing and Urban Development and discovers a dismal scene of squalid, crime-infested low-income buildings maintained under HUD. They include some of the most run-down buildings in the nation, and they fall below the government's own safety codes.
The show also finds missing or inoperative safety equipment and repairs that are made mainly in election years or after publicized tragedies. Charges of HUD corruption are raised, along with questions of the department's continued usefulness.
The people interviewed include HUD Secretary Henry Cisneros and former HUD Assistant Secretary Frank Keating, as well as Chicago Housing Authority chairman Vince Lane, several activists, and many of the people who count most: HUD-housing tenants. Bill Kurtis is host. * SATURDAY
Wimbledon (NBC, 2-6 p.m.): The network is marking its 25th anniversary year of coverage of this event, which opens with these early-round matches. Some 33 1/2 hours, live and on tape, are planned for the world's most prestigious tennis tournament. For Wimbledon itself, this is the 108th championship, taking place at the All England Lawn Tennis & Croquet Club in London.
