With no competition from the Olympics, American Idol returned full-strength on Tuesday, scoring a 15.9/24 in the 8:00 p.m. hour and an 18.6/27 from 9:00 p.m. to 9:30 p.m. In the process, the show clobbered NBC's latest great hope, the game show Deal or No Deal, which managed to register only a 6.1/9 at 8:00 p.m. (The game show, airing every night this week at 8:00 p.m., was also beaten by CBS's hit NCIS, which produced a solid 9.7/14.)
