Litecoin (LTC)

In October of 2011, Litecoin was released by Charlie Lee, a former Google employee. This coin introduced a 2.5 minute block time, compared to the 10 minutes per block with Bitcoin. It also increased capped circulation to 84 million. The two currencies are similar in many ways. Litecoin could be considered the 'Silver' coin, 

while Bitcoin is still referred to as digital 'Gold'.
