In 1985, Texas lawyers used the telephone and fax machine to communicate, first-year associates at BigTex firms made about $42,000 annually and the largest Texas firms had about 400 lawyers.

Twenty-five years later, lawyers stay in touch via text messaging and e-mail, the Texas market rate for first-year associates is $160,000, and large Texas firms have more than 500 lawyers in the Lone Star State alone.
