Seven scamware apps found in Google Play and Apple's App Store corralled more than half a million dollars for their developers, according to Avast. The company discovered the malicious apps after a 12-year-old girl flagged a suspicious app promoted on a TikTok profile through its "Be Safe Online" project.

Google's domination of the online ad market appears to have stalled since Amazon last year became the third-largest digital ad platform in the U.S. behind the Google-Facebook duopoly. This may have driven Google to accelerate its push into e-commerce, focusing on what it calls the "messy middle" -- the space in the customer journey between what triggers the purchase and the actual purchase itself.

Nintendo seems to be uncomfortable with the dominant business model in the mobile-gaming market, which allows players to download and start playing a game for free, then entices them to spend money on the software through in-app purchases. Those tactics have come under the increased scrutiny of regulators, which also concerns Nintendo, a brand with a family-friendly image.

Apple's Intelligent Tracking Prevention feature has made it difficult for online advertisers to use cookies to target Safari users. Third-party cookies "serve as the foundation for almost all advertising use cases," noted Jordan Mitchell, head of consumer privacy, identity and data at the IAB Tech Lab. The blocking "negatively affects the ability for brands to target audiences."

Mark Zuckerberg recently said that the future of Facebook is private. Interestingly, connecting the dots between all the announcements made at Facebook's 2019 developers conference draws a bright picture of what the future looks like for brands, small e-commerce stores, and new businesses using the Facebook family of apps. It includes a whole new world of opportunities.

The social media model has come under increased scrutiny following revelations of data misuse and news of executives reneging on some security commitments. People expecting to change the situation will need to address how social media works. This means changing not just the business model, which describes how a social media business makes money, but the fundamental technology model too.

There's one competitor we underestimated this year. It's slowly draining the attention of every human on the planet. It plays into almost all human needs -- as they are defined by the Maslow Hierarchy. It's the rectangular status-seeking device in your hands. That's right. It's your smartphone. Maslow's needs start with the basics. Starting at the bottom of the pyramid, we all need food and water.

Vero, a relatively unknown social network, has been enjoying a surge in user engagement in recent weeks, a trend that may be tied to growing user discontent over recent changes to Instagram's algorithm, along with an assortment of other objections that have been driving users away from the leading social platforms.

Google on Thursday announced a new feature that will let users mute so-called "reminder ads" in third-party apps and websites that are powered by its ad engine.

Advertising technology, or ad tech, is a relatively new business segment. Both Google and Facebook have been very successful with this new advertising model.

As it approaches its IPO, Snap, maker of the popular Snapchat messaging app, is positioning itself as a camera company. "We feel like we're really at the beginning of what cameras can do," said Snap CEO Evan Spiegel. "Before, cameras were the best way to perfectly save or record something that you saw. They sort of helped augment memory -- but now, you know, cameras augment the way that we talk."

Facebook this week announced new features for News Feeds videos, along with an app for TV. News Feed videos now have sound turned on by default in mobile devices.

Snap this week hired Morgan Stanley and Goldman Sachs Group to manage its IPO, according to multiple reports.
