Tenis is more attractive to watch because ball is bigger and slower. Then table tennis needs this:
1. Good cameras angles. Because after nice rally you need slow motion.
2. More time between serves. Sometimes they need time for slow motion. In tennis it is not problem but in table tennis is it problem because of "6 balls towel use" rule. Then spectators didn't see how it was nice because everything is really quick.
3. Big TV screens in hall where after nice rally spectators can see slow motion. Otherwise is table tennis very quick and not interesting for spectators. I love table tennis but I don't like watch it live because in TV I can see slow motion.
4. There is too much easy errors in table tennis. Normal spectator don't understand why best players doing so many easy errors. They don't understand rotations of ball and other things. I think todays table tennis is very, very quick and there is too much rotation in ball (but speed is real problem). We will need some regulations for rackets materials (I will not suggest how to regulate it). If you check some really old videos of table tennis then you will see very long and interesting rallies and not too much easy errors (some of them because of ball hidding during serving). Try to check old Waldner's, Person's or young Ma Lin's videos (many other players) and you will see what I am thinking. Todays Chinese players (but not only them) playing almost every attack ball like killer shot. Then players like Boll, Mizutani, Hyuk, Samsonov (many others without killer shot but nice playing technique) have problem. If material is slower then it will be not possible and for winning ball you will need more playing variations (Waldner was really great!
) and then it will be very interesting to watch.
5. Better quality for online video. It was ITTF's great step these online videos but they will need to improve quality to 720p or more because table tennis's ball is small and very quick. Its sometimes boring watch matches with poor quality.
6. More player types variability. 99% today's players at Pro level playing same style. We need more modern defenders, more asian type defenders (big loops), more all round players or some new player types. If someone want to watch interesting match then very offen watch matches of modern defenders or all round players. Why everybody play same? Because of attacker's advatage. Its easier play attact type of play than others.
Maybe now when everybody will have HD tv at home table tennis will be more popular to watch. We will see.
