Place of Employment Bought by Another Company

Question
My current employer bought my previous employer. What is the best way to show this on a resume without duplicating my entire work experience/responsibilities? The only thing that changed is the company name.

Thanks for your help.

Answer
For the sake of this answer, let's say the name of your current employer is New Horses, Inc., and the name of your former employer was Old Horses, Inc. And, let's say you started working for the old company in 2000.

In your work history, list your time at that company like this:

2000 - present, New Horses, Inc. (formerly Old Horses, Inc.)
