Series 6 & 7
Series 6 started off strong, the Christmas Special gathering around 12 million viewers for Matt Smith's first Christmas Special, whilst the main series itself kept figures of between 6.5 to up to around 8 million per episode. Series 7 was split into two halves with a Christmas Special between, but for the purposes of gathering data I've considered it one whole series. The first Christmas Special had over 10 million views, and the first regular half kept figures upwards of 7.5 million. The second half was less steady, the Christmas Special bringing in nearly 10 million viewers, and the rest of the series following the same general pattern as those previous, before reaching almost 7.5 million in the finale.
