(Wines&Vines) - Mambo Media founder Siouxsie Jennett has been part of the Internet sector nearly since its inception; the past three to four years have spurred levels of change she has not seen since the web’s heady early days. Jennett shared her secrets about online marketing this morning with an audience at the Unified Wine & Grape Symposium. In years past, marketing campaigns created spikes of activity followed by lulls in attention. Social media has changed that, Jennett said, allowing brands to create a continuous way to connect with consumers without dips in activity between large promotions.
