We're going to look at a couple of kinds of traffic. In a moment, we'll hear about the unexpected benefits of gridlock in Indonesia's capital, but first let's look at the variety of traffic on the Internet.
DAVID GREENE, HOST:
A new report out this week suggests that nearly two-thirds of Internet traffic isn't people clicking mouses or tapping on screens, it's actually bots. Bots are automated software programs that comb the Internet, sometimes doing good, like Internet searches, people googling, and sometimes they're malicious, viruses or worms, spamming and stealing personal data.
MONTAGNE: The new study from tech company Incapsula finds that bot activity is on the rise up 20 percent over last year.
GREENE: But it notes that much of that rise is of the positive kind. They see less spamming activity than they did in 2012. Transcript provided by NPR, Copyright NPR.
