All 3 girls made the forbes celebrity 100, which is a rank of the most "powerful" stars. To generate the list they use the amount earned over the last year, how many times they have been searched on the internet, how many times they've made the news and how many magazine covers they've graced. They didn't give (/I can't locate) figures for anything other than the pay, but I'll try and get them.
Here's where they came:
63. Maria Sharapova ($19 Million)
87. Serena Williams ($10 Million)
90. Venus Williams (($7 Million)
Some things to note:
These 3 were the only tennis players on the list, no men managed to make (while as last year I think Roger, Andy and Andre made it)
All 3 of the girls are down from last year in the rank, although pay remained about the same.
Maria is still the highest paid female athlete although Michelle Wie is now the 2nd (pushing Serena into 3rd) with $17 Million.
There were only 5 female athletes in the list this year ( the other 2 are Michelle Wie at 74 and Annika Sorenstam at 91)
Well done girls
