Cloud video service provider Brightcove agreed to buy cloud video ad insertion company Unicorn Media, Brightcove said in a news release Monday (http://bit.ly/1cI8gHC). Brightcove will pay $9 million and 2.9 million shares of Brightcove stock for Unicorn, for a total of $49 million, Brightcove said. “We believe that online video has the potential to surpass traditional TV by offering mass personalization, superior ad targeting, and frictionless distribution to more screens in more locations,” said Brightcove CEO David Mendels. The buy of Unicorn will allow Brightcove to help media companies deliver ad-supported content to the many platforms consumers use to watch online video, said Mendels. Unicorn’s Once ad insertion service “reduces or eliminates the need for platform-specific ad technology” and lets media companies deliver live or on-demand video with “dynamically customized programming and targeted advertising to the maximum range of devices,” Brightcove said. Unicorn’s Once service will be rebranded under the Brightcove name, it said. Brightcove expects Q4 2013 revenue to be close to $30 million, it said.

Cyberwarfare is believed to be the most serious national security threat the U.S. faces, said a Defense News poll released Sunday, with 45 percent of poll respondents listing it as the top threat. The poll, sponsored by United Technologies, surveyed 350 “senior defense leaders” who deal with national security issues, including members of the military and congressional staffers, Defense News said. About 42 percent of respondents who identify as Democrats said cyberwarfare was the top threat, as did 36 percent of Republican respondents and 55 percent of independently affiliated respondents (http://bit.ly/198kRsK).

Amazon now collects sales tax from customers in 19 states, with the addition of Indiana, Nevada and Tennessee on Wednesday, the company said (http://amzn.to/1d25DXh). States are continuing to legislate their own retail tax laws after the Supreme Court chose not to hear New York’s Amazon/Overstock case, which would have helped define what it means for a company to have a “physical presence” in a state.

Netflix is testing a $9.99-a-month streaming plan, in addition to the $6.99 one it announced earlier this week, spokesman Jonathan Friedland said Tuesday. Subscribers opting for the $9.99 plan can stream content to three screens at the same time, he said. Under the $6.99 test, subscribers can only stream to one screen at a time. Just like the $6.99 plan, “not everyone will see” the $9.99 plan at Netflix.com when signing up for a plan and “we may not ever offer it generally,” said Friedland. The $9.99 test, like the $6.99 one, is only available to new subscribers, he said. Netflix marketing tests usually “take anywhere from several weeks to several months,” said Friedland. “Whether we roll out any of these options depends on the test results."
