The pay-TV firm's pre-tax profit for the nine-month period hit £339m, up from £20m in 2008, when the figure was low due to an impairment charge of £474m.
Third-quarter revenues rose from £1.25bn to £1.39bn, while pre-tax profits increased from £56m to £63m.
Net customer additions for the third quarter were 80,000, 43% higher than the rate in the prior year, taking BSkyB's total customer base to 9.3m.
The company said it had seen a very strong customer response for HD TV, from both new and existing customers, with 243,000 net additions in the third quarter.
In January, it set a purchase price of £49 for a Sky+HD box, which led to the accelerated take-up. Over 1m UK households now have Sky+HD.
BSkyB also added 130,000 new customers to its broadband service.
Roughly 15% of the company's customer base now takes all three products of TV, broadband and telephony, which is up from 9% a year ago.
Churn, or the number of customers who dropped Sky, was 10.6%, broadly in line with the prior year.
Jeremy Darroch, chief executive of BSkyB, said that the company expects conditions to remain challenging during the rest of 2009.
Darroch said: "In this environment, and at a time when people are spending more time at home, we will continue to provide our customers great entertainment and money-saving broadband and telephony.
"At the same time, we will stay focused on cost efficiency to allow us to invest sensibly in areas that drive long-term value for the business, such as high definition, with the objective of emerging stronger from the downturn."
Sky's popular programmes include 'Lost', '24', 'The Simpsons' and one of its own commissions, 'Skellig', starring Tim Roth.
