It seems that the overwhelmingly popular tennis players, the ones people buy tickets to see(williams sisters, agassi...) in crowds, receive favorable line calls when they are in danger of losing a match, especially early in a tournament. One example, of many I have seen, was last year at the Advanta Championships. Venus Williams was playing Yuliana Fedak. Fedak was close to defeating Williams and Williams was hitting long of the baseline SEVERAL times and not one of those shots was called out. The points continued until Fedak made an error or williams got the winner. It happened at each breakpoint opportunity for Fedak and in the 3rd set tiebreak. I was seated to the side of the baseline just a few rows up. I had a terrific view of the entire baseline, like that of the official calling the baseline. Many many people around me and myself were gasping with disgust at the failure of the official to call williams' shots out. It was horrible. Fedak would have won the match. However, the tournament would have lost one of it's biggest name players early in the event.
