AT&T sues over Charter's use of 'fiber

AT&T sued Charter in Texas court, alleging deceptive advertising for using 'fiber-powered' to describe HFC broadband. AT&T claims this misleads consumers, causing irreparable harm. Charter argues it's on solid legal ground. Both companies are competing in the broadband market, with AT&T expanding fiber and Charter upgrading HFC. AT&T previously raised this issue with the National Advertising Division, which Charter addressed, but AT&T is now pursuing legal action.
