Amazon and the "profitless business model" fallacy
Strangly, this was the business model of cable companies for the longest time.   They never turned a profit.  When they expanded, they could use the increased income stream to go <i>deeper</i> into debt.  The profits and extra capital went into more expansion.   Eventually, they ran out of room to expand, and where are they now?<p>Someday, Amazon will need to face the brutal reality of profit.
