With just a click of button, YouTube could collect children's private information.

"Kids are online as much as they can be,” said Carolyn Hedges, a Syracuse University Communications assistant professor. “That's all my kids want to do."

The amount of children who watch online videos has doubled in the past four years, according to a study by Common Sense Media.

YouTube recently changed its policy to better protect children and their privacy.

"In September, they were slapped with a $170 million fine for not complying with COPPA, which is the Children's Online Privacy and Protection Act which is supposed to be a safety net for kids not to be marketed towards online,” said Hedges.

It was part of an agreement with the Federal Trade Commission and New York's Attorney General.

In about four months, YouTube will limit data collection and use of personal information from people who watch children's videos, despite their ages.

"They're going to have all creators designate their content as being children directed,” said Hedges. “They have to physically toggle every single video and indicate whether or not it's intended for children."

They'll also stop serving personalized ads and support features, such as comments and notifications which could hurt creators.

"You've got these targeted ads that are not bringing in revenue,” said Hedges. “You are also not being part of playlists. There's a whole kind of spiral effect that happens after they take away this information that is detrimental to making the millions and millions that they're making."

Some parents feel this is a step in the right direction.

"You can start to look at YouTube as a little bit safer place for kids to be, remove some of the concerns as I have as a parent," said Michael Fey, a parent. “Again, it does put the onus on the content creators to do this correctly.”

But, parents also say the best protection is them.

"There are some dark places they could fall if their hand isn't held,” said Fey. “Keep an eye on what your kids are doing and be involved in their online life."

"It's our responsibility to understand what we're consuming what our children are consuming,” said Hedges.

YouTube recommends parents continue to use YouTube Kids if their children are under 13-years-old and are watching alone.

They're improving the product and bringing it to the desktop.
