On this special episode of "Recode Decode," we celebrate the relaunch of Recode.net with an extended interview between Recode co-founders Kara Swisher and Walt Mossberg. In 1991, Mossberg was laughed out of the Secretary of State's office for announcing that he would start writing about technology. Three media companies and 25 years later, he reflects on the changing landscape of tech journalism. Plus: Kara and Walt preview the upcoming Code Conference and look back on a decade of conference highlights and lowlights.
