Does Test cricket need to go day-night?

Is Test cricket really the only game played over several days? I was reading Mr. Modi's interview regarding eyeballs to Test cricket necessitating a move to a day-night format. Is that the cure that will set right the ills of this format? He also mentioned advertiser friendliness as a motivator for broadcasters to carry it consistently - is this an issue?

I am not certain that these are, infact, unique to Test cricket. There are other sports played over multiple days - golf is one example. Each golf tournament is played over four days - it just so happens that the four days always include Thursday, Friday, Saturday and Sunday. In other words, all tournaments get a weekend, some tournaments get to enjoy the crowds over a three-day weekend.

The crowds are not huge at the venue as most holes do not have galleries and the sport being played over many acres is not exactly the most spectator friendly. Even so, TV contracts are still sizeable.

Would Test cricket alone fetch similar contracts today? A highly doubtful proposition. But then, what makes golf succeed in preserving its long format while cricket struggles to keep it true to tradition? A prime cause is the dilution of the competitive quality of Test cricket. Second, is the negligent attitude shown by having some Test matches played from Monday to Friday, missing out on the weekend crowds. Third, is scheduling - a uniform schedule will go so much farther across nations.

There are more, but of one thing I am certain; if golf can do it with its smaller audience, cricket can do a whole lot better if only the right questions are asked. Gimmickry is not the solution in my opinion, though Mr. Modi, as a seasoned cricket administrator, has had the experience to hone his views.
