Bill Cosby and Larry Hagman of “Dallas” are the top television stars of the 1980s, according to TV Guide. The magazine ranked Cosby first, hailing him as “the most successful entertainer in history,” and praised runner-up Hagman for the “campy finesse” with which he portrays J. R. Ewing. The rest of TV Guide’s list of 20 top TV personalities of the decade: Oprah Winfrey, Ronald Reagan (“the first made-for-TV president”), Joan Collins, Ted Koppel, Vanna White, David Letterman, Michael J. Fox, Tom Selleck, the California Raisins, Sam Donaldson, John Madden, Hulk Hogan, Don Johnson, Dan Rather, Roseanne Barr, Morton Downey Jr., ALF and Pee-Wee Herman.. . . .
