AT&T Inc. is the second largest wireless service provider in North America and one of the world's leading communications service carriers. Through its subsidiaries and affiliates, the company offers a wide range of communication and business solutions that include wireless, local exchange, long-distance, data/broadband and Internet, video, managed networking, wholesale and cloud-based services. With assets like HBO, CNN and TNT, AT&T's acquisition of Time Warner has created new kinds of online videos and opened up avenues for targeted advertisements. The company is also focusing on streaming services with AT&T TV and HBO Max. This is likely to create other avenues to monetize content as it expands 5G coverage across the country.
