Today's Tech: IBM's 5-year predictions, Facebook selling video ads, and Amazon getting in on mobile payments

Video ads on Facebook

Facebook will start selling video ads later this week in a move that has been mooted for some time and is the latest attempt to grab a slice of the valuable TV advertising market worth some $66.4 billion [£40.8 billion] in the US alone. People familiar with the matter have told the press that ads will start appearing on the web and mobile devices from Thursday and that videos will play automatically in users' news feeds but be muted.

Thinking ahead

IBM has revealed its "5 in 5" predictions for technology to look out for in the next 5 years. Among the predictions are computers that learn and know everything about you, smart classrooms that will help level the playing field in schools, and cities that know each of their citizens. Exciting advances are forecast in medicine, web security and retail, too.

Gobuygo

Italian newspapers are reporting that Internet giant Amazon has just acquired a new mobile payments startup, Gopago.

Gopago is a mobile app that gives consumers the chance to pay for their goods before picking them up at a store. Customers benefit from easy shopping on the go, and retailers sit pretty on a new point-of-sale system in their arsenal. But what are they planning? Could it be part of the ambitious new "Log In And Pay With Amazon" service that competes with companies like PayPal?

A little manners...

A man and a woman have been charged with improper use of a communications network after sending abusive messages to feminist campaigner Caroline Criado-Perez. The campaigner rose to prominence after successfully campaigning to have author Jane Austen included on future UK banknotes. Following the success of the campaign, she suffered a vicious array of abuse on the social media network, including death and rape threats. The pair of accused will appear in court on 7 January.
