There’s a terrible temptation to believe that this entire article was written so that this one pun could be included:

The fact that the
market-leader should be the relatively celibate Closer (which
emphasises dating over mating) will come as a shock to Channel 4 and
the advertising industry, who still seem to believe that sex is what
sells. Does the success of Closer hint that the obsession in women’s
magazines with sexual technique and the perfect orgasm has finally
climaxed?
