On programs that were hastily arranged and broadcast on the two largest federal channels, he was compared to the dissident Andrei Sakharov, to Julius and Ethel Rosenberg, and to Max Otto von Stirlitz, a dashing fictional double agent from Soviet television.
He was described as "the man who declared war on Big Brother and got stuck in the transit zone," and as "a soldier in the information war, who fights, of course, on the side of Russia, or maybe the side of China."
For as long as he remains here, one program's host said, "the pulse of world history is beating here in Moscow."
Since Snowden landed in Moscow on Sunday, the likelihood that he will remain in Russia has steadily crept up.
Though President Vladimir V Putin said this week that "the sooner he chooses his final destination, the better for us and for him," Snowden shows no sign of leaving.
The chance that Russia will turn him in has all but vanished, as evidenced by Thursday's television programs, which were almost certainly produced under Kremlin orders and have a powerful effect on public opinion.
Officials here have signaled an openness to granting him political asylum, and each passing day would seem to narrow Snowden's options, giving the United States time to negotiate with Ecuador and Venezuela, other countries that may grant him asylum.
"I think the main thing for him right now is to guarantee his security," said Igor Korotchenko, a former specialist in Russia's top military command who now edits the magazine National Defense.
"Already, he cannot live his former life. The United States of America will look for him all over the world in order to punish him as an example to potential traitors, and so that the political elite in Washington will be satisfied. They want his blood."
"Whose protection does he want: Ecuador, Venezuela or Russia? It is hard to judge right now," Korotchenko said. He added, "In Russia, he will find a country capable of guaranteeing his security because I think in Latin America the United States would find much opportunity to solve the problem, so to say."
So far, there is no consensus among Russian elites on whether Russia should grant Snowden asylum, a step that would advertise the country, Cold War style, as a haven for Western dissidents.
Russia's upper house of Parliament has invited him to testify about the impact of spying by the National Security Agency on Russian citizens, and about the activities of giant Internet companies that may have shared information with the agency.
Though Putin has made it a central goal to challenge US dominance in world affairs, the potential cost of granting Snowden asylum has come into sharper focus over the past few days.
Putin and many of those around him are former intelligence officers, and they may see Snowden as a traitor, and an unpredictable player.
Igor M Bunin, director of the Center for Political Technologies in Moscow, said that by far the best solution for Moscow would be to send Snowden to another country, "to Ecuador, Venezuela, to Cuba, wherever."
"Snowden is like a hot meat pie in your hands: even if you want to eat it very much, it's very hot and maybe it's better to throw it on the floor," Bunin said. "To make a deal with America to turn Snowden over would be a slap in the face of public opinion because he is already a hero in Russia and part of the West. On the other hand, not turning him over destroys your relationship with America."
Unlike Ecuador and Venezuela, Russia has avoided staking out a position on political asylum for Snowden, and in his remarks at a news conference Tuesday, Putin said he hoped not to become personally involved.
But on Wednesday the Kremlin apparently decided to hastily arrange two hourlong talk shows devoted to the case. Each focused less on Snowden himself than on the flaws of the United States and the threat posed by its intelligence apparatus.
Alexander I Shumilin, a political analyst who was invited to appear, said he had turned down the request, sensing that the result would be a "mighty propagandistic blow: not a shot from a pistol, but a shot from a cannon."
One program featured a panel of legendary counterintelligence agents, including a man famous for meeting with Lee Harvey Oswald a few months before the assassination of
President John F Kennedy.
Their discussion often turned to the subject of US spying on Russia. Korotchenko, one of the guests, made the case that most of the major US consulting firms in Moscow were actually "structural units of American intelligence," including the National Security Agency.
"The NSA is a global electronic vacuum cleaner, which monitors everything," he said "Look at the top two floors of the new building of the US Embassy - it's a huge antenna, which listens to the Moscow air."
Similar themes were sounded a few hours later on Channel 1, when the pro-Kremlin analyst Vyacheslav A Nikonov warned that the United States, through its dominance over the Internet, could "strongly undermine the security of other states."
"The Internet is an invention of the US Ministry of Defense," Nikonov said. "Where is the Internet? Physically, it is in the United States. What is the Internet? It's an American nongovernmental organization which is, of course, connected with the intelligence services of the United States."
