Internet is there today due to small and medium size ISPs. Most of the big Telecoms was never been interested in a platform which was threat to their cash cows (PSTN, SDH, ATM, Frame-Relay etc.). Today all of the big telcos talk about IP/Internet and would like to milk as much as they was doing before, they just don't know how.
Future consolidation will shows that only Internet/Infrastructure Provider and Over The Top (OTT) providers will dominate the connectivity market. A walled garden approach will be successful only in very rear cases.
