Mediacom became the latest operator to add a mobile product to its portfolio. Marketing has already begun and employees are using the service, and customers are expected to be able to get in on the action in early June. It’s been a long and carefully planned process for Mediacom, a similar sentiment felt at C-SPAN before it chose its next CEO Sam Feist. Feist will officially begin leading the public affairs network in September—right in time for the heat of election season.
