The international is free to watch, i know alot of other tournaments have a pay-to-watch ticket if you wanna watch via the ingame client, or you anw atch for free on their streams, some tournaments give you cool things if you buy a ticket, IE - The Defense season 2 ticket holders got a special edition "Defense" War dog Courier.
As well as what cyanide said- theres flags and sections on the map (like the each teams fountain) That has space where teams casn put their logo/sponsor logos etc, i know EG is showing their logo and the Monster logo at the mid-river, while their base has the raidcall logo. Its pretty cool, some other teams just show all their logos on all positions (Which is difficult to make out which is which in some locations, they're too small)
Great job by Valve. See the amazing venue, Seattle's Benaroya Hall.
Groupstage is over, rehearsals are over, its time for the main event.
