Even though Facebook video ads play automatically, marketers still plan to increase their spend on the social media giant in this arena. Many also plan to invest more dollars in social video across other platforms as well, according to a just-released report from eMarketer surveying the state of social video advertising.

Consumers are voting with their wallets in favor of subscription video services. Driven by the strength and near-ubiquity of Neflix, subscription VOD services have become more popular than ad-supported online streaming from sites like Hulu, according to a Hub Research study. The report found that in 2015, about 47% of U.S. consumers subscribed to an online streaming service, and that number jumped a whopping 21 points to 68% this year.

Streaming video viewing and TV viewing go hand in hand -- except when they don't. While a number of studies have shown that streaming video viewers are avid TV watchers as well, many who actively use over-the-top services say they'll downgrade their multichannel video services in the coming months.
