How to remove the big banner from Software Center?

In the new version of Ubuntu Software Center there is a big banner under toolbar. It's useless for me. How do I remove it?

This banner ad was bugging the hell out of me too. I figured out how to remove it, but this might void your warranty or whatever so do this at your own risk:

1. Close Ubuntu Software Center and make a backup copy of
   /usr/share/software-center/softwarecenter/ui/gtk3/widgets/exhibits.py

2. Edit that file as root: sudo gedit /usr/share/software-center/softwarecenter/ui/gtk3/widgets/exhibits.py

3. Find the line which defines MAX_HEIGHT = 200 (line 229 or so)

4. Change MAX_HEIGHT to 10

5. Save the file, restart software center, banner no longer obtrusive.

sudo nano /usr/share/software-center/softwarecenter/ui/gtk3/views/catview_gtk.py

find self._append_banner_ads() and comment it out with #.

#self._append_banner_ads()

Save file, restart Software Center. See http://www.youtube.com/watch?v=QVT0HZDqMq0 for more information

In Ubuntu 12.10 and 13.04, the file is: /usr/share/software-center/softwarecenter/ui/gtk3/views/lobbyview.py
