[7] Three year later, he rejoined TheStreet as a commentator and editor of Herb Greenberg's "Reality Check" newsletter.
[10] In March 2022, he launched Herb Greenberg Investment Opportunities, a subscription-based service that recommends stock choices to paid subscribers.
[11] While at The Chronicle, Greenberg launched an investigation into Media Vision, a maker of sound cards and multimedia kits for CDs.
[17] In February 2006, Greenberg and other reporters were served subpoenas from the Securities and Exchange Commission (SEC) demanding records of phone and e-mail communications with sources for an investigation of which the journalists were not the target.
In a rare public reprimand, SEC chairman Christopher Cox said that he was not consulted prior to the issuance of the subpoenas by the SEC's San Francisco office, stating, "[The] subpoena to a journalist which seeks to compel production of his or her notes and records of conversations with sources is highly unusual.
In an editorial, The Wall Street Journal said that the "SEC scolds are harassing journalists who report market-moving facts based on their daily digging."
