Adweek reported that YouTube’s mobile users spent more 40 minutes per session on average in the second quarter, an increase to the tune of 50% year over year.

In addition, there are more advertisers taking an interest in YouTube and they are, unsurprisingly, also spending more money. Advertisers rose 40% for the video platform, while the top 100 advertisers spent 60%, according to the publication.

“Our strong Q2 results reflect continued growth across the breadth of our products, most notably core search, where mobile stood out, as well as YouTube and programmatic advertising,” according to CFO Ruth Porat in a statement. “We are focused every day on developing big, new opportunities across a wide range of businesses. We will do so with great care regarding resource allocation.”

YouTube, which has 1 billion users, boasts having more 18-49-year-olds using the site than those who subscribe to cable. “Advertisers want to reach these audiences, and our focus is on the opportunity to get larger budgets moved to YouTube,” according to Porat.

Google (GOOG), which owns YouTube, notched a strong earnings report as a result.
