A record 199 million requests were submitted to BBC iPlayer in September, with average daily requests reaching the highest ever level, at 6m a day.
Television again provided the vast majority of requests, but radio grew by 8% over September to deliver its highest ever monthly requests, at 50m.
This came ahead of the launch of BBC iPlayer Radio, the new home for all BBC radio content online.
The first episode of Doctor Who series seven delivered the highest number of TV requests for a single programme, at 2.2m.
Doctor Who also dominated the top four spots, including episode two racking up 1.77m requests, episode four taking 1.35m and episode three pulling 1.34m.
On radio, the final episode of The Chris Moyles Show on BBC Radio 1 topped the list, with 427,000 requests, followed by coverage of Andy Murray's win in the US Open Final, which pulled in 274,000 requests.
The latest BBC iPlayer data also shows that mobile and tablet accounted for over a fifth of iPlayer requests in September (21%). This was only just behind TV platform operators such as Virgin Media (+22%), but ahead of games consoles (+16%).
