Instagram continues to pitch itself to brands and agencies as a complement to TV campaigns, but with its cheaper prices and more personalised offering, experts believe it could steal ad dollars, as long as brands understand its points of difference. Instagram launched 60-second ads last week, with Guinness being the first UK brand to use them. The activity, part of its 'Made of More' campaign, will run on TV, digital, social and PR.

Sir Martin Sorrell questioned the "judgment" of companies such as Google, Amazon and Starbucks that use "very aggressive" methods to limit the amount of corporation tax they pay.

Next week BBC3 will go online only -- causing, according to critics, "massive damage to the development of future television audiences and of new talent, both on and off-screen." BBC3 controller Damian Kavanagh disagrees. He says that when it was first announced that he "felt a bit when we were having conversations that this was sad for talent or there would be lost opportunities for talent." He added: "In truth when I see the kinds of things we're commissioning [especially] short-form there's more opportunity for talent in a way."

Morale at Express Newspapers is at its "lowest point" for 20 years, according to the group's National Union of Journalists Father of Chapel.

Officials from the Premier League are in talks with cyber-security companies in an effort to stop fans from watching top-flight football on illegal online streams. The discussions are believed to centre on tightening "geofencing" procedures.
