Building its existing success, WFAA dominated the market's local news ratings from the mid-1970s—having overtaken WBAP-TV/KXAS' once-dominant "The Texas News"—through the late 1990s. The station strengthened its on-air news staff with top-tier talent, led by anchors including Tracy Rowlett (one of three reporters—along with Doug Fox and Byron Harris—whom news director Marty Haag brought over to WFAA from his previous job as news department head at KWTV in Oklahoma City in 1973), Iola Johnson (who became the first African American news anchor in Dallas in 1978, serving as a lead anchor with Rowlett), Bob Gooding, Murphy Martin, Judi Hanna, John Criswell, Chip Moody, John McCaa, Gloria Campos, Lisa McRee, Verne Lundquist, Dale Hansen and Troy Dungan (who, as chief weather anchor from 1976 to 2007, developed modern-day chroma key techniques for televised weather forecasts, the five-day forecast concept and created the "News 8 Doppler Net," a network of National Weather Service radar sites throughout Texas). Other notable people who once worked at Channel 8 include Scott Pelley (who was recently anchorman of the "CBS Evening News"), the late David Garcia (who went on to become a network reporter for ABC News), Mike Lee (who covered news in Europe for many years at ABC News' London bureau), Doug Terry (who became a founding reporter/producer at NPR's "All Things Considered" and created several Washington-based television news services), and the late Don Harris (who, while working for NBC News at the time, was killed at the start of the Jonestown massacre and mass suicides in Guyana in 1978).
