Last week, the Wall Street Journal ran a story on the LA cable market, which is split by 5 companies. It very much resembles the Dutch market. Some quotes:
"Satellite-TV and telephone-company rivals have been able to outmaneuver
cable companies, which have been hamstrung in their marketing efforts and their
ability to introduce new technology."
"Gaining critical mass in major markets is crucial for cable operators,
which face competition not only from their traditional satellite-TV rivals but
also from phone companies that are upgrading their networks to offer faster
high-speed Internet service and television."
"More than 30% of the households in the region get high-speed Internet
connections from telephone companies, compared with a 20% share for cable
"Until now, the five cable operators in Los Angeles have been reluctant to
use regionwide advertising because their pitches would be wasted in
neighborhoods not able to get their services."
