The document discusses different levels in marketing distribution channels. A channel level refers to a layer of marketing intermediaries that brings a product to the final buyer. Common channel levels include zero-level (direct from manufacturer to consumer), one-level (manufacturer to retailer to consumer), two-level (manufacturer to wholesaler to retailer to consumer), and three-level (manufacturer to wholesaler to jobber to retailer to consumer). Longer channels with more intermediaries are more common when retail markets are fragmented with many small retailers.
