Woods, who had back fusion surgery in April 2017, began the year in promising fashion, finishing tied second in the Valspar Championship in March before briefly leading the Open in July and coming second behind Brooks Koepka in the US PGA in August.
But Woods tackled a packed schedule as the season reached its conclusion, bemoaning the heat that contributed to mental, physical and emotional exhaustion.
"I love the vision of GolfTV and the ambition for it to become the premier destination for golf entertainment worldwide", Woods said in a statement.
He qualified for the WGC Invitational and the FedEx Cup end-of-season playoffs and played for seven out of nine weeks from early August.More news: Holy cow! Giant steer 'Knickers' stands head and shoulders over herd

But what no one can control is Woods' continued professional success after a five-year drought. It will present more than 2,000 hours of live action each year as well as a wide range of premium content on-demand, featuring the sport's most exciting moments, superstar players and tournaments on every screen and device. "Not quite hitting it as far, but I had the adrenaline going and, overall, I'm very pleased".
As for the relationship between the two, which has evolved and strengthened through the years, Woods said, "We're excited to have Hero with us for the next four years". I was worn out mentally, physically, emotionally, but thank God the Ryder Cup started on Friday so I had an extra day to get my juices flowing again.
But Woods considered his 2018 efforts to be thoroughly worthwhile, saying: "It has been the most rewarding [year], because there was a point where I didn't know if I would ever do this again".
On his charity foundation, he said: "It has been more impactful than what I have done on the golf course; but what I have done on golf course has allowed me to do this".
"You always hear me say that it's a process but, if you look at this entire year, it literally was a process". "You can see that with Tiger, where he's just such a good player". "The association with Hero has been a win-win situation for both of us and I am elated", Woods added. "To have my own platform to communicate is the culmination of a lot of hard work from my team and the team at Discovery".
