ABC digital network director Angela Clark has quit the public broadcaster, the first executive to leave under new boss Michelle Guthrie’s tenure.

According to The Guardian, Clark was credited with the runaway success of the ABC’s digital offerings (the ABC has just become Australia’s most popular news website, surpassing both and The Sydney Morning Herald‘s website.

Says The Guardian:

“Clark’s digital strategy for transforming the public broadcaster was approved by the ABC board at its August meeting a week ago. The strategy details how the ABC can survive the disruption of digital media and break down the silos of radio, TV and online into one seamless service.

“But within days Clark had tendered her resignation, saying she wanted to pursue opportunities in the commercial sector. Guthrie has made no comment about Clark’s resignation.”
