CNET Networks said Tuesday that the Securities and Exchange Commission ended an inquiry into the company's stock option grants.

Regulators won't take any action against San Francisco-based CNET, which is a media company.

CNET's founder Shelby Bonnie quit as chairman and CEO last October -- on the same day the company said it had back dated some stock options grants between its 1996 IPO and 2003.

The costs of the ensuing stock options investigation and related litigation cost CNET Networks $2.9 million in the second quarter, ended June 30, and pushed it to a $76,000 loss.

CNET's loss would have been greater but for a $1.6 million gain on private investments, which partially offset the costs of its stock options investigation.

Neil Ashe, Bonnie's replacement as CEO, said it was a "transition year" for his company.
