ABC scored a record-setting news magazine Nielsen rating of 25.9 for Diane Sawyer's live interview with Michael Jackson and Lisa Marie Presley Jackson on the June 14 telecast of "Primetime Live." ABC, the dominant network for the week, had a 9.2 rating, ahead of an 8.4 for NBC and a 7.4 for CBS. But the combined prime-time audience share for the Big 3 networks fell below 50% to a 48 share for week 39 of the 1994-95 TV season. The Big 3's combined Nielsen rating for the week fell 8.7% to a 25.1 from a 27.5 the same week last season. Despite airing the NHL's Stanley Cup Finals, Fox also fell 9.8% to a 4.6 rating for the week ending June 18. Basic cable, meanwhile, continues to surge, with a 31 share for the week and a 15.9 rating, up 6.7% from last season.
