PowerPoint improved Word Art in 2007. This shows how to get text to animate in a circle.
Start by creating a text box and adding the text:
Next decide on the diameter of your circle (be realistic – will the text fit!) Right click the edge of the text box and use “Size and Position” to set the (equal) width and height. With the textbox still selected use FORMAT > TextEffects > Transform to select Follow Path > Circle.
Now select the textbox (not the text itself) and change the font size until the text just fills the circle. Finally use the green handle to rotate the shape so that the start of the text is just to the right of top centre.
