에이티앤티(AT&T) - Spelling Bee

With long-distance rates falling and the market for telecommunications services overall weakening, AT&T could not sustain the debt it had incurred in these ventures. Moreover, the cost of upgrading TCI's equipment to handle two-way communications proved far higher than pre-merger estimates. AT&T undertook a major reorganization in October 2000, moving its mobile phone and broadband units into separate companies, to allow each unit to raise capital independently.
