What would you do to improve the rules of Tennis, to make it a better TV viewing experience?

I would recommend the following things be changed in the rules of tennis to make it more interesting. (1) Reduce the length of a 'set' to be 4 games long, and the first person to 4 wins the set, with no requirement to lead by 2 clear games over their opponent. (2) I would only allow one serve - instead of two - per player when starting each point. (3) I would stop players from wasting time between points by limiting their towel breaks to 23 seconds long. (4) If a player's service hits the net and goes over, they win the point (this means no replaying of points due to hitting the netcord and flopping over the net). (5) I would declare a rally null and void if it goes over 20 shots; it would count for nothing and both players would have wasted their efforts without any positive outcome. (6) I would not allow players to take a break, between games, until 4 games had been consecutively played, regardless of their physical capabilities. (7) The maximum number of tennis sets that can be played in major Tennis tournaments be limited to three. (8) If a tennis match exceeds three hours in duration it gets called a "tie" - no winner, and rewards are halved.
