£200 million?!
Sadly that wouldn't go 'into' ntl, but into shareholder's pockets. Minor other issue of course that £200 million would do you for about 6% of ntl, which is worth considerably in excess of £3 billion.
A takeover of a NASDAQ company, or even owning of any considerable sum of shares would require various market declarations to be made by bother parties. Centrica valued at £9 billion I don't think would have the stomach to spend that much on ntl, especially when ntl seem more interested in merging (takeover paid for with shares) with Telewest and making a £5 biliion cableco (various rumours about this one, a lot pointing in the same direction, which unlike this drivel I believe).
HOWEVER the idea of gas powered broadband is top notch, especially after the curry I had last night, would that be considered uncapping the modem though?
