Wondering how old Trevor Noah is? You're not alone. In fact, so many people are Googling that question that Comedy Central has come up with a response: "I am 72 years old," Mr. Noah says in a YouTube clip that surfaces as a search ad when you Google the phrase, "How old is Trevor Noah?"

It's one of several video responses that will appear in search results starting this week as part of Comedy Central's robust marketing push to introduce fans of "The Daily Show," and some potentially new, younger viewers, to Mr. Noah before the show re-launches on Sept. 28.

As big as the campaign will be, the largest in years for Comedy Central, the network is simultaneously trying to target certain messages to precise audiences. "It's a broader, more targeted and largest campaign we have done in some time," said Michele Ganeless, president, Comedy Central. "It's our marquee program so we are leaving no stone unturned."
