In Marvel comics:
* Thanos consuming the entire set of multiverses in the omniverse and consuming the Living Tribunal himself. Each multiverse is an entire infinite set of universes, and the omniverse covers all of the multiverses.
* Scarlet Witch "rebooting" the multiverse several times in a row, in House of M.
* Reed Richards re-writing the entire multiverse using the "true" Galactus' 616 version of the Universal Annihilator, in order to defeat Abraxas.
* Pre-retcon Molecule Man unleashed a blast against Beyonder that destroyed thousands of universes.

In comics in general:
* There have been so many universe-destroying blasts that I've started to lose count. Off of the top of my head, Monarch having his armor breached by SuperboyPrime and literally blowing up the entire universe as a result was one such recent event.
* The anti-monitor was destroying universes one by one, in Crisis on Infinite Earths.
* In Marvel, the future timeline that was cut off from mainstream MU-616 had Galactus consuming the entire universe after he ate a Celestial and went mad. In a moment of sanity, he activated the Universal Nullifier and wiped out not only that universe, but the shock was traveling backwards through time and echoing through the multiverse. Galactus had grown so powerful in his madness that he was literally consuming space and time, so time itself was in danger of being erased (he was as big as a planet at that point).
* In comics, destroying a planet is considered to be a high end top tier feat. Many of the top tier heroes have done so, for example Hulk recently not only incinerated a planet as a side effect of him punching someone, but also incinerated other above-top tiers on the planet. Beta Ray Bill has destroyed planets, as has Sentry, Thor has fought planet-destroying monsters, etc.. Destroying an entire planet in comic books really isn't that big of a deal anymore.

In Anime:
* Gurren Lagann the movie - started off with a "big boom" attack, where the energy projected was equal to the fires of creation. Later on the final attack consisted of an entire multiverse of energy.
* There was DBZ, if you count the anime version (which is non-canon to the manga from the fillers and movies), Goku summoned an entire galaxy worth of energy to destroy a demon. They would destroy planets fairly often in that show; one of the characters Brolly went around destroying every star system in an entire galaxy (basically an anime version of the Hulk).

In movies:
There have been many planet eaters, and many planetary level explosions, probably too many to count. I don't know of any universe-level destroying blasts, or more powerful than that.

Marvel: The End...

Thanos destroys the universe only to find out that The One Above All manipulated him into doing it to correct a fundamental flaw in the universe. Thanos restores the universe, erasing himself from existence, a sacrifice remembered only by Adam Warlock.

More Marvel that you people forgot although a part mentioned by Juddog:
http://www.comicvine.com/the-galactus-engine/12-55741/

Galactus Engine.

The Galactus Engine had left every species that confronted it, including The Celestials, in ruins. The Celestials themselves now lacked their primary Judge thus leaving Arishem's position along with countless others to now be filled, at least until they could recover from the war.

As for the "lesser" races...millions upon millions of people, people that were loved and cared for deeply by many, had been exterminated in the blink of an eye by forces they could not understand or imagine.

Though it is gone, The Galactus Engine's dark and twisted legacy along with records of its actions will be remembered by every generation until the end of time and space and light and life.

If you're going to allow books, I can name a couple where entire universes are destroyed.

The one most matching the spirit of the OP is probably Manifold: Time by Stephen Baxter.

Actually, reading the trivia for that:

The explosion in the Fhloston main hall was the largest indoor explosion ever filmed. The resulting fire almost got beyond control.
