Charlie Meredith, publishing director at IPC TX, said: "The price increases on What's on TV and TV Easy are yet another sign of TX's determination to drive retail sales value in the TV weeklies market."
These price rises follow similar increases in September 2006, when the cover price of the titles was increased by 2p to their current value, delivering an extra £1.85m in sales revenues.
But this was followed by a decrease in sales for What's on TV during the second half of last year. The market-leader's average circulation was 1,437,650, down 4.8% on the first half of 2006 and 4.3% down on the second half of 2005.
Its nearest rival is TV Choice, published by H Bauer and priced at 35p, with an average circulation of 1,353,436. This is up 5.1% on the first half of 2006 and 11.6% up on the second half of 2005.
TV Easy's average circulation was 293,325, down 2.7% on the first half of 2006 and up 3.1% on the second half of 2005. It is currently outselling Bauer's TV Quick, priced at 75p, by around 47,000 copies.
