Here is a detailed description of the Max Headroom incidents and their aftermath, that we were asked to dig.

Will speculate on relevance.
Text "We are here with you" appeared on various televisions lately.
How was it done technically and who did it.
Today stations produce TV/cable content centrally as well as at local affiliates. The video content is digital data and is transmitted over highspeed links to the local TV and cable stations. The local stations then transmit the video signal, complete with inserted local programming and local advertisements and local station ID, to a TV transmitter location or to a cable head-end site where it is fed into the CATV distribution system for local distribution. The link from local stations to transmitters or CATV can be a wireless microwave link (as in the Max Headroom example), a highspeed link leased from a phone company or privately owned, or more typically today a fiber optic link.
How is it possible for someone to interrupt a digital data stream and modify it to overlay text?
Military units have the capability. I have posted extensively on it before, identifying the PSYOPs unit at Fort Bragg and the special aircraft that can transmit civilian radio and TV signals as part of a PSYOP.
The NSA also has the capability. All comms pass through central offices and switching sites, and there are NSA taps so that NSA can record all the comms in the country (and elsewhere). I don't know if it's legal for them to insert/modify programming but it is certainly feasible technically.
Forgot to add: The links for digital data video programming can also be satellite.

Reposting prior dig on Mil PsyOp unit at Ft Bragg, NC and their capability to produce and distribute civilian broadcast programming.

Moar on US military psyops capabilities.
Could these systems be used in America during a state of emergency? Anon figures the answer is yes, and maybe soon.
How The Military Conducts PSYOPS

Joseph Trevithick, Jan 24, 2017
When people think about U.S. Army equipment, what probably comes to mind are tanks, gunship helicopters, self-propelled artillery, and other larger advanced weapons - all great for blowing things up. However, American troops often rely on a very different gear to both confuse and demoralize enemy troops and "win the hearts and minds" of civilians on and around the battlefield.
Thanks to an unclassified 2005 training aid, Task & Purpose is able to highlight the unique equipment military personnel bring on these psychological operations, or PSYOPS. As of 2017, Army Special Operations Command oversees all active PSYOPS troops, though some units are attached to the Army Reserve.
According to the unclassified PSYOPS training manual Task & Purpose obtained under the Freedom of Information Act, these troops employ everything from printed messages to radio programs to television shows to "create a behavior that supports the United States" and promote American military objectives, as the manual puts it. Elite troops have their own Special Operations Media Systems-B that combines both radio and television studio functions in a suite of relatively mobile equipment.
Four Humvees and two trailers can hold all the various pieces of the Mobile Radio Broadcast System and the Mobile Television Broadcast System. Special operators can deploy the two components wherever commanders might need them with the help of U.S. Air Force C-130 and C-17 aircraft, according to the guide.
The radio station portion produces, records, and transmits the alerts all by itself, according to the Army guide. While the mobile television production center does the same for audio-visual messages, it also has extra cameras, lights and other gear so specialized soldiers have the option of creating their own news reports from the field.
When American special operators arrived in Afghanistan after the 9/11 terrorist attacks, they brought the SOMS-B with them. By 2002, the U.S. military was broadcast radio programming in local languages, such as Pashtu and Dari, 24 hours a day as part of Operation Enduring Freedom.
To make sure messages went out around the clock, the PSYOPS soldiers on the ground got help from the Air Force's EC-130J Commando Solo planes - noted in the Army's training manual under "sister service capabilities." These heavily modified C-130 cargo planes beam down radio and television signals from a unique, in-flight studio.
The Afghans loved the American-supplied news and other alerts, mostly because "they broadcast music and for almost everyone," according to Weapon of Choice: U.S. Army Special Operations Forces in Afghanistan, a book published by the Army. For six years, the Taliban had banned radio stations from playing popular tunes and local folk songs.
The Army handbook points out SOMS-B has the ability to record content on CDs or tapes so troops can distribute it to friendly broadcasters. In 2016, American crews were dropping leaflets encouraging locals in northern Syria to tune in to FM 99.1. This is the frequency for Radio Rozana, a pirate radio station independent journalists run as an alternative to official Syrian government outlets.
In addition to the smaller down-range setups, the Army has larger production facilities situated at Fort Bragg, North Carolina, as well as the large but deployable Theater Media Production Center, or TMPC. Compared to the SOMS-B, this four-part system cranks out longer and more complex audio and video materials in both digital and physical formats, including CDs or even older cassette tapes.
The mobile unit also has scanners and high-resolution printers to make copies of photographs and printed messages. Another limitation of the smaller SOMS-B is that troops cannot produce substantial numbers of printed PSYOPS messages.
As of 2005, the 3rd Psychological Operations Battalion owned the Army's sole TMPC system. But PSYOPS soldiers need permission from president or the secretary of defense to roll it out, according to the Army manual, and we could find no open reports of its deployment.
Of course, the Pentagon continues to rely on older, more traditional PSYOPS tools, too. By the end of 2016, American aircraft had dropped thousands of leaflets over Iraq and Syria warning innocent civilians of impending air strikes and calling on them to resist Islamic State terrorists.
