Billions and billions of apps served

Maybe that global Big Mac index will need to be replaced with an App Store index. From the temporally named PC Magazine:

The iconic golden arches come stamped with the phrase "billions and billions served." The signs used to include a number, which Lai says McDonalds stopped updated in 1994 when it reached 100 billion burgers. It took McDonald's 26 years to serve the same number of burgers as the number of apps that have been downloaded from the App Store, and it took the fast food restaurant an additional 20 years to hit 100 billion burgers.

"That means Apple hit the 15 billion mark about nine times faster than McDonald's," Lai said. "And based on projections, Apple could hit 100 billion within five and a half years, or about nine times faster than McDonald's."

Lai also noted that "based on projections of its accelerating growth, Google could hit 100 billion downloads even sooner than Apple."
