Ten Network has posted a $264.4 million net loss in its half-year results, on the back of a $251.2 million write-down in the value of its television licence.

While Ten did not elaborate on the write-down in its statement on the results, it would reflect the decline in the fortune of free-to-air broadcasters as video streaming becomes more prevalent.

The one-off impairment is non-cash and, excluding it, Ten had television earnings before tax, depreciation and interest expenses of $7.5 million, although this was also down on $10.1 million in the same period last year.

The decline in earnings is due to a fall in television revenue to $309.8 million from $315 million in the first half last year.

Ten's cost cutting measures could not keep pace, despite lowering television expenses by 2.1 per cent.

The network's chief executive Hamish McLennan chose to focus on the metrics that were showing signs of growth.

"Network Ten was the only commercial network to increase its people 25 to 54 and total people audiences during the 2014-15 summer and achieved a 24.7 per cent revenue share in January 2015," he said in a statement.

"The primary Ten channel has also had its best start to a ratings year since 2012."

Mr McLennan has welcomed the Federal Government's acknowledgement that licence fees need to be looked at.

"Australia's licence fee regime remains by far the most punitive in the world," he argued.

"Paying licence fees on top of corporate tax and increasingly onerous Australian content obligations is unreasonable."

Mr McLennan has also supported a review of media ownership laws, however he warned against changes that would allow some companies to pursue consolidation while others were still restricted.
