Facebook’s move last year to discourage passive consumption of content, especially videos, has impacted engagement. Average daily time spent on the platform by US adult users fell by 3 minutes in 2018. And that time will remain unchanged this year, per the latest eMarketer forecast on US time spent with media. In fact, we have reduced our forecast for Facebook compared with the previous figures released in Q3 2018.

According to an April 2019 survey of global consumers from mobile video ad network AdColony, three in five respondents said they encounter offensive content on Facebook, and about half that figure noted the same was true of YouTube. Inappropriate content appearing on Google, in mobile games, or on platforms like Instagram and Snapchat was less likely, but still apparent.

Fewer people in the US are accessing social networking sites via computers, with the majority of users now exclusively on mobile devices. We forecast that 51.7% of US social network users will be mobile-only in 2019.

According to a spring 2019 report from investment bank and asset management firm Piper Jaffray, 73% of Gen Zers (those ages 7 to 22, per the report) said they prefer brands to contact them about new products through Instagram, with Snapchat following as the preferred method at roughly 50%.

Following its unpopular redesign, Snapchat has been struggling to gain users in the US.

There is an exodus from Snapchat in the UK.

Gen Z is a tough generation for retailers to figure out. They grew up on the internet, but don't like to be targeted with ads there, and crave authenticity in all of their interactions. We parsed the research to help retailers figure it out.

Not only will Google and Facebook continue to dominate in the UK, but their combined share of the digital ad market will also continue to rise. This year, it will reach 63.3%, up from 62.7% last year, according to eMarketer’s latest UK digital advertising forecast.

Snapchat has been busy lately trying to woo marketers. While we predict that Snapchat will cross $1 billion in US net ad revenues in 2020, reaching this milestone took longer than anticipated.

Social commerce only drives a fraction of ecommerce sales, but it's picking up speed. Between 2016 and 2018, social networks as a last-touch channel have doubled in visit share to US retail sites, according to Q3 2018 data from Adobe.

Social video ad spending in the US will reach $14.89 billion in 2021, growing 44% from 2019, according to our latest forecast. It will then account for 30.4% of total video ad spending.

Influencer marketing is growing around the world, and a significant amount of activity is migrating to Instagram Stories. However, fraud is also growing, and that threatens the authenticity of influencer marketing.
