AT&T today said it is introducing its U-verse IPTV service in Detroit and Ann Arbor, Mich., where it is taking on cable provider Comcast.

The announcement comes about a month after AT&T announced U-verse was reaching 18,000 customers following its expansion into Milwaukee, Kansas City and Dallas-Fort Worth and three weeks after it announced its first deployments in California.

In Michigan, as in California, AT&T cited the state video franchise law, passed last December, as one of the things affecting its deployment decision.

AT&T is hoping to capitalize on a larger High Definition TV content list, along with four-room Digital Video Recorder capabilities to capture video customers and position its bundle favorably against Comcast, which has been highly successful selling its triple-play services and winning voice customers.
