The Tiger Effect on golf ratings is indisputable [Video]

Tiger Woods didn’t win any of the year’s four major golf tournaments, but his presence was the only story that mattered this summer. The ratings numbers prove it.

Over the three major tournaments this summer where Woods was in contention, the “Tiger Effect” averaged out to a 40% final round bump.

CBS and NBC reaped the benefits. ABC and ESPN, which stopped broadcasting the British Open last year, may wish it had held on to the rights for a little longer.

As Woods finished better and better over the course of the summer, the television ratings bump for the final round got bigger and bigger.

When Woods was in contention in the final round of The Masters in April, CBS’s ratings on Sunday ended up 14% higher than the year before, according to Nielsen. He finished tied for 32nd.

At the British Open in July, NBC’s ratings on Sunday were up 37% over the previous year. Woods tied for sixth.

And at the PGA Championship, CBS’s ratings soared by 69% as Woods chased Brooks Koepka on his way to finishing in solo second place.

Woods missed the cut at the U.S. Open in June. Ratings for Fox on that Sunday were up just barely over the year before, and it was the third-lowest rating on record for the final round of the U.S. Open.

The lesson is clear: When Woods is absent, the casual fans tune out.

It began with the Valspar Tournament in March. On the way to Woods tying for second place, NBC saw a record 5.11 overnight rating on Sunday, the best rating for a non-major PGA Tour event since 2013. Sunday of the Valspar was also the best-rated golf telecast other than The Masters, since the 2015 PGA Championship.

In addition to finishing second at the Valspar, second at the PGA Championship, and tying for sixth at the British Open, Woods tied for fourth at the Quicken Loans National and tied for fifth at the Arnold Palmer Invitational.
