Well, although Bell was broken up into many "smaller" pieces, those pieces appear to be simply re-merging, and re-congealing back together again, slowly but surely.

I suppose the initial break-up however is good, and would stimulate a more competitive environment, and allow new start-ups to join the game.

But eventually those pieces are simply drawn back together again... It's like when you break a magnet into many pieces -- they reattract back together.
