Because the Confederates cut the wires in Georgia, so Sherman was incommunicado for 5 weeks,until he reached the coast and made contact with Washington via the Union Navy.
Telegraph Agency of the Soviet Union was created in 1925.
In most situations, the communications afforded to US Civil War generals was a good thing to have. Communications are essential for a military campaign. In certain situations, however, it could be troublesome. For example at Fredericksburg in December of 1862, US President Lincoln was able to give General Ambrose Burnside direct orders to attack the entrenched Confederate forces. This was a costly mistake as at least 10 to 12 direct assaults by Burnside were a disaster. It is very likely that as his own field generals recommended, it was a bad idea to attack. Lincoln's interference via telegraph doomed several thousand Union solders. This was Burnsides first major battle as commander of the Army of the Potomac.
The telegraph system created by Samuel Morse had been vastly improved from its earlies days of 1838. The Union used the telegraph extensively to communicate from field armies to Washington DC for example. In fact, in one unsuccessful Union battle, the one at Fredericksburg , Virginia, President Lincoln stayed in touch with General Ambrose Burnside via telegraph. In this case, however, the "advanced" communications, allowed Lincoln to inform Burnside to assault entrenched Confederate forces under Robert E. Lee. Despite the advice of Burnsides generals, he proceeded with the assault based on Lincoln's orders.
The country that had most of the telegraph lines was Western Union Telegraph Company.

Western Union, primarily known for its money order services, was established in 1855 when two competing telegraph companies decided to merge. The two companies that merged were both established in 1851 under the names "New York & Mississippi Valley Printing & Telegraph Co." and "New York & Western Union Telegraph Co." which was simplified to "Western Union Telegraph Co." upon their merge.
