Yeah, they were small local breweries in that time before refrigeration and easy transportation, though, not national level breweries. In fact, if you go back to their pre-Victorian days, Hacker brewery was only a seasonal brewery. My statement was based on having worked in Germany for several years, and being a fan of these brews long before that time. I was never able to find any German who drank Hacker-Pschorr or Paulaner. They mostly seem to stick to their local brews, although they all know Lowenbrau, Stuttgarter, Weinstephaner, and Erdinger.
