As they grew, the larger and more successful firms began to take over smaller breweries, although they often retained the older brand names and the loyal clientele of those brands, such as Carlton & United Breweries (CUB) continuing to distribute "Tooth's KB Lager" and "Resch's Pilsener" and "DA" ("Dinner Ale") after they had bought and eventually closed the Reschs and Tooths breweries. By the mid-20th century the brewing industry was dominated by a handful of large and powerful state-based companies: Tooth's and Toohey's in Sydney, Carlton United in Melbourne, Castlemaine in Brisbane, West End and Coopers in Adelaide and Swan in Perth. These brands effectively became unofficial mascots for their respective states. In Victoria, until the late 1990s, a distinction was largely observed of serving the similar CUB lagers Carlton Draught on tap and Victoria Bitter and, to a lesser extent, Melbourne Bitter in bottles and cans; as Victoria Bitter became a prominent national brand on tap, in turn it became considerably more common on tap in Victoria.
