'American Idol' steams ahead for Fox, NBC's Wednesday woes continue

American Idol held a huge audience for its two-hour edition last night (Wednesday), Nielsen overnight data reveals.

Hollywood Week continued with 18.6m (6.0), achieving the same rating as last week's one-hour instalment, giving Fox an even more convincing primetime victory.

On the other end of the scale, low ratings for Whitney (4.5m/1.6), Are You There, Chelsea? (3.5m/1.4), Rock Centre (5.9m/1.7) and Law & Order: SVU (5.9m/1.7) ensured a poor night for NBC, which saw it being beaten by cable channel Univision.

Survivor: One World premiered for CBS with 10.7m (3.0), before Criminal Minds hit a season low of 11.9m (3.0). Bucking the trend, CSI climbed to 11.1m (2.7).

Meanwhile, The Middle (8.1m/2.5), Suburgatory (6.9m/2.4), Modern Family (11.2m/4.7) and Happy Endings (5.8m/2.5) all fell to lows on ABC.

Elsewhere, One Tree Hill maintained a steady 1.4m (0.7) for The CW at 8pm, then the audience dropped to 500k (0.2) for Remodeled.
