When Netflix (NASDAQ: NFLX) first introduced its video-streaming plans in 2007, its stock traded at around $3 per share. However, few investors had the foresight to realize just how revolutionary the concept would become: With 130 million members in more than 190 countries today, Netflix closed this week at a whopping $380 per share.Of course, there's a case to be made that Netflix still has plenty of room to climb from here.
