In a ho-hum piece about how The X Factor has "changed the music business forever" (apparently being on TV sells records - why did nobody think of that before?) the Telegraph's James Hall calls on an expert witness:
Artists with new albums to plug – from Bon Jovi to Robbie to Whitney to Michael Buble – now appear on a weekly basis. Gennaro Castaldo, a spokesman for HMV and a guru on sales trends, says that artists who appear on the show can expect a “doubling or trebling” of sales on the back of their performance.
That's totally changed the face of the music business, right? Nobody ever fought to get a band on a half-assed Saturday night TV show in order to boost sales before. Unless you count Noel's House Party, or Parky, or all the other ones.
