We have a broader program, called G2G or Googler2Googler, where Googlers enlist en masse to teach one another. In 2013, 2,200 different classes were delivered to more than 21,000 Googlers by a G2G faculty of almost three thousand people. Some classes are offered more than once, and some have more than one instructor. Most Googlers took more than one class, resulting in total attendance of over 110,000.
