Telegraph | Money | O2 buys £50m broadband minnow

''They are the fifth biggest DSL [digital subscriber line] provider and are estimated to get to first or second place within a couple of years." Bought by Telefonica last year, 02 said the deal would allow it to offer broadband to its 16m customers and compete with the likes of Orange and Carphone Warehouse, which launched its high-profile broadband offer last year.
