Networking hasn't changed. But the way you approach it should. As a CEO you have to be discerning about  the rooms you enter. Be intentional about your long game and be mindful about who you associate with. If you're not clear about your "why" for networking, you won't find yourself in the appropriate rooms, circles or events. The last thing you want to do is waste your time and energy with anything that will prove fruitless. Focus on getting in better rooms and making connections that lead to real deal.
