Salon Media Group, publisher of the Web site Salon.com, announced Friday that it received an $800,000 investment round from its existing investors. Shareholders Bill Hambrecht and John Warnock, who is also a board member, led this latest round. The media company, which has raised a total of $2.1 million since July, said the funding should help it achieve its plans to break even. The media company, which has more than 60,000 premium subscribers, had its stock delisted in November. It now trades over-the-counter under the ticker SALNC.
