The Internationals or TI is the Dota 2's most prestigious tournament as it is primarily sponsored by Valve (the makers of CS Go and Dota 2 ) and offers ground breaking Prize money year after year. No Game Franchise in the E-sports industry offers this much prize money in their tournaments like DOTA 2. The first ever TI held on Cologne, Germany had $1,000,000.00 in Total prize money and was virtually unheard of at that time.
This makes TI6 even more awesome as it boasted the largest total prize pool in history at the time. A whopping $20,770,460 USD . This record will eventually be beaten by none other than TI7 set to take stage August 07 2017 currently at $20,877,862 USD and growing. 
Held in the Key Arena in Seattle WA and took place on August 2nd 2016 TI6 hosted 16 teams each vied for supremacy and the coveted Aegis eager to earn their spot in history.
