I would say English from a broad perspective or a major focused on the area of journalism you'd like to get into since you'll be doing a lot of reading regardless. Like if you wanted to get into reporting on world events or politics I'd go for something related to political science or international relations. If you wanted to talk about the markets you could even go the route of economics, etc. Regardless, I would either say English or a subject area focused on what area you'd potentially like to focus in. Hope that helps!
