The big beasts of the telecom industry kick off their most important annual get-together in Barcelona on Monday. A popular idea for many at the show is to get the owners of bandwidth-hungry platforms like YouTube, Netflix and Facebook to pay network operators a "fair share". Christel Heydemann, boss of French operator Orange, says the five largest users -- which she does not name -- account for 55 percent of daily traffic on European networks, costing telecoms firms 15 billion euros ($16 billion) a year. She says it is an "unsustainable situation" and welcomes a public consultation launched by EU commissioner Thierry Breton last week. Jose Maria Alvarez-Pallete, boss of Spanish operator Telefonica and current chairman of industry body GSMA, hails "a new change of era driven by the intersection of Telco, Computing, Artificial Intelligence and Web3".
