For more than four­teen years, Spark has worked as a jour­nal­ist report­ing on the tech indus­try in print, radio, TV, and online. His arti­cles and advice have appeared in more than 25 pub­li­ca­tions and media out­lets includ­ing eWEEK, Wired News, PC Com­put­ing, PC World, ABC Radio, and Smart Com­put­ing. You may have seen Spark dis­pens­ing his “how-to” advice and pun­ditry on ZDTV/TechTV, a for­mer cable sta­tion about com­put­ers and the Inter­net (video).

In addi­tion, Spark spent ten years in adver­tis­ing and cor­po­rate enter­tain­ment as a new media direc­tor and mar­ket­ing creative.

While not cov­er­ing the tech beat or man­ag­ing ad cam­paigns, Spark squan­dered more than a dozen years work­ing as a stand up come­dian and com­edy writer for The Sec­ond City com­edy troupe in Chicago (video).

Cur­rently, Spark is a reg­u­lar con­trib­u­tor for John C. Dvorak’s Cranky Geeks, KQED’s “This Week in North­ern Cal­i­for­nia,” ABC Radio, hosts his pod­cast “Be the Voice,” and can be heard daily on the “Spark Minute” for two Clear Chan­nel radio sta­tions in the Bay Area: Green 960 (pro­gres­sive talk) and 910 KNEW (con­ser­v­a­tive talk).

David Spark lives in San Fran­cisco, a city he loves so much he’s become a local his­to­rian offer­ing walk­ing tours to locals and tourists.
