Courtesy once again of AndrewM (the first!), updated sales figures/ratio’s for Quarter 3 – 2009.
Ofcom recently released their Digital Progress Report for Q3 2009 (http://www.ofcom.org.uk/research/tv/reports/dtv/dtv_2009_q3/).
Including the information you previously published (http://www.joinfreesat.co.uk/index.php/freesat-sales-sdhd-ratio, http://www.joinfreesat.co.uk/index.php/freesat-sales-sdhd-ratio-update and http://www.joinfreesat.co.uk/index.php/freesat-sales-figures-q2-2009), here are the updated Freesat sales figures as they stood at 30 September 2009:
Freesat unit sales – 2008
Q2 2008: 39,000 units (15,000 SD and 24,000 HD) (61% HD) 
Q3 2008: 69,000 units (20,000 SD and 49,000 HD) (71% HD) 
Q4 2008: 125,000 units (26,000 SD and 99,000 HD) (79% HD) 
Total sales for 2008: 233,000 units (61,000 SD and 172,000 HD) (74% HD) 
Freesat unit sales – 2009
Q1 2009: 117,000 units (26,000 SD and 91,000 HD) (78% HD) 
Q2 2009: 98,000 units (79% HD) *
Q3 2009: 193,000 units (79% HD) *
Total sales since launch:
As expected, Freesat sales figures showed a big increase in this quarter, with total unit sales by the end of the quarter standing at 643,000 and setting a new quarterly sales record of 193,000 units, nearly double the previous quarterly sales figure. Ofcom reports that the proportion of HD receivers is still constant at 79% (see note below). And as you reported in late November (http://www.joinfreesat.co.uk/index.php/freesat-sales-pass-750000), Freesat said that sales had by that point surpassed 750,000. Given these figures, I definitely think that Freesat is on track to pass the million mark sometime this current quarter.
*Note that starting in Q2 2009, Ofcom only reports the percentage of HD receivers sold, rather than giving a number of units, so it isn’t possible to give the units breakdown of SD and HD receivers. Also, it’s not completely clear if the percentage they give is for total sales or quarterly sales; I have assumed the latter.
