IBM vs T Comparison

IBM looks to be a part of every aspect of an enterprise's IT needs. The company primarily sells software, IT services, consulting, and hardware. IBM operates in 175 countries and employs approximately 350,000 people. The company has a robust roster of 80,000 business partners to service 5,200 clients, which includes 95% of all Fortune 500. While IBM is a B2B company, IBM's outward impact is substantial. For example, IBM manages 90% of all credit card transactions globally and is responsible for 50% of all wireless connections in the world.

The wireless business contributes about two thirds of AT&T's revenue. The firm is the third-largest US wireless carrier, connecting 72 million postpaid and 17 million prepaid phone customers. Fixed-line enterprise services, which account for about 16% of revenue, include internet access, private networking, security, voice, and wholesale network capacity. Residential fixed-line services, about 11% of revenue, primarily consist of broadband internet access, serving 14 million customers. AT&T also has a sizable presence in Mexico, with 22 million customers, but this business only accounts for 3% of revenue. The firm still holds a 70% equity stake in satellite television provider DirecTV but does not consolidate this business in its financial statements.
