The other show "George Lopez" they use his real first and last name o.O So my question here is. Why do... show more How come on some shows the main character use their real name?

So my question here is. Why do some shows like those three I've mentioned, use their real name and the other shows like Wizards of Waverly Place and Lizzie Mcguire use fake names? Any idea? Thanks in advance.
