This week in social media news, Twitter tests encryption, Snapchat drops licensing fees, Instagram adds more action and YouTube presses play on Vevo ads.

Twitter: Secret Codes, Silly Quotes

Encrypted direct messages (DM) may soon become an option for Twitter users, TechCrunch reported on Monday. An eagle-eyed Twitter user spotted a test template for encrypted DMs in the back-end code of the Android version. Although Twitter did not officially confirm the feature, the company’s CEO Jack Dorsey tweeted a link to the TechCrunch article with a “shushing face” emoji.

In the wake of Facebook’s Cambridge Analytica scandal, Twitter and other sites are bumping privacy to the top of their lists of things to fix. Last week, Twitter found a bug that left passwords available for internal viewing. Although the company claims no one misused the information, Twitter encouraged everyone to change their passwords immediately.

On a lighter note, Twitter code also reveals the ability to quote tweets with a GIF. The yet-to-be announced feature was spotted by the same computer science student, Jane Manchun Wong.

Snapchat: Discover Your Own Fees Now

Publishers featured on Snapchat Discover channels will no longer be paid upfront licensing fees, making ad revenue their sole source of income on the app.

Snap, Inc. initially paid these fees as an incentive for publishers to create daily and weekly content on the platform. Now the incentive is for media partners to sell advertising, as publishers now share ad revenue from Snapchat Discover.

YouTube:Turning up The Music Ads

Google’s video sharing site has a complicated relationship with the music industry, but a new deal may help change that—at least when it comes to selling ads.

YouTube has penned a deal with Vevo, the music video joint venture between Universal Music Group and Sony Music Entertainment. Under the new agreement, YouTube will be able to sell Vevo clips directly to advertisers—previously available only to Vevo’s sales team.

During its NewFronts pitch, YouTube announced that it will now sell Vevo clips as part of its “Google Preferred” tier.

Instagram: More Talk, More Action

Instagram introduced call to action buttons to select business profiles last week that allow users to book appointments, make reservations and make purchases without leaving the app. On Tuesday, additional companies added action buttons including Fandango, Acuity, ChowNow and several others.

The company reported that more than 150 million users have conversations with brands each month using Instagram Direct. On Tuesday, Instagram announced changes to the Direct inbox designed to help brands reply in a timely manner and keep messages organized.

A new feature called “quick replies” will be tested in the coming weeks that allows businesses to respond to frequently asked questions
