This is Keith Raffan posing a question about S4C on Sharp End this week:
What do we notice about the "question" he posed? Well, it is true that Gaelic has fewer speakers than Welsh, and that BBC Alba has a smaller budget. But does it have a bigger audience?
As it happens, BBC Alba's viewing figures are not collected by the BARB because the BBC doesn't want them collected, and therefore hasn't asked them to do it. But they have used the polling organization TNS System Three to assess the figures instead. As we can read here, they have reported that the channel has weekly reach of about 200,000 ... and another report, here, puts the figure at 220,000.
Either figure is less than half the weekly reach of S4C, as we can read here.
