Protocol president Tammy Wincup is quick to remind people that her just-launched tech publication isn't a subsidiary of Politico but a standalone news site.Still, Protocol, also funded by Politico owner Robert Allbritton, will be applying the Politico playbook -- offering a morning newsletter (Source Code) and seeking a wide audience for a set of premium, insider products of the sort found in a trade publication.With a staff of more than 30, Protocol will be able to "begin thinking much earlier about what our audience needs from the services and tools perspective," Wincup said. She added that Protocol is a business-to-business publication more than a business-to-consumer one -- although it blurs the lines between the two genres. "Your business audience is also your subscription audience [and] is also your, in many cases, sources."Wincup joined the Digiday Podcast to discuss the infiltration of tech into every industry, the Source Code newsletter and Protocol's plan to credit tech companies where credit is due.
