The original partnership deal, which dates back to 2009, ended in December, but had been temporarily renewed while the two companies negotiated a renewal. The companies did not provide details about the terms of the renewal.
The size of the investment, which YouTube did not disclose, was between $40 million and $50 million, according to Billboard.
"We made an investment in VEVO. We are excited by their future prospects and to provide YouTube users with the best possible music experience," YouTube said in a statement.
Vevo, which is a joint venture owned by Universal Music Group, Sony Music Entertainment and Abu Dhabi Media Co, did not return requests for comment.
Vevo streams music videos on its own website. It also has a co-branded "channel" on YouTube that features music videos from popular artists, including Rihanna, Adele and Lil Wayne.
Vevo was the most popular partner channel on YouTube in the United States in May, with 50 million unique viewers, who spent an average of 36.1 minutes on the channel, according to industry research firm ComScore.
YouTube is the world's most popular online video destination, with more than 4 billion video streams every day. While much of the fare on YouTube consists of amateur home videos that users upload to the site, YouTube has stepped up efforts in recent years to provide professionally produced videos.
