That last mile problem, getting news from telegraphs to people's homes, was solved by newspapers. e.g. The Daily Telegraph[1] is specifically named for that purpose.
They were printing reports from all over the world.
As an example the modern sporting event the Tour de France was started by a newspaper in 1903 and was reported on daily. That wouldn't really have been viable financially without mass communication. In fact the race exists solely to generate those reports.
There's a very good book called The Victorian Internet that covers early mass communication if you're interested[2].
> A mix of June and 19th, Juneteenth has become a day to commemorate the end of slavery in America. Despite the fact that President Abraham Lincoln’s Emancipation Proclamation was issued more than two years earlier on January 1, 1863, a lack of Union troops in the rebel state of Texas made the order difficult to enforce.
> Some historians blame the lapse in time on poor communication in that era, while others believe Texan slave-owners purposely withheld the information.
Telegraphy had allowed current news to rapidly flow around the globe for decades.
