That's because it aired in January.

Here in the UK we have 3 seasons a year: two celebrity and a civilian.

The first celebrity season airs in January and is the highest rated in terms of number of viewers. The second one is the civilian and airs in early summer and is the lowest rated. The third one is another celebrity season and airs in late summer and is the middle rated.

So the one in January always has more of a buzz about it.
