This year the 149th Open Championship that was to be held at Royal St George's Golf Club in Sandwich, England, got cancelled due to obvious reasons. Last time the Open Championship was cancelled happened during the World War II.
On the official Open Championship site you can still enjoy some great content like one of my favorite documentary series "Chronicles of a Champion Golfer" and Open Championship recap videos from 1970 until now, among other video materials.
To start watching for free, you just add your email adress (this is also your login username and password). No other information is no longer required to join their "The One Club", a reason why I personally hasn't used this free service until now.
