JD, Venom more influential? Really?! If anybody in the shock rock genre it would be Alice Cooper and Kiss. Venom was a bleep on the radar.
Venom kickstarted the entire Black Metal movement. Hardly a bleep on the radar
Venom did not start the BM genre, they had an album called Black Metal.
They were always strictly NWOBHM with some thash infuences.
They are also by far the worst live band I have ever seen.
I've never even heard of Venom. Now, it's not like popularity has anything to do with musicians' influences, but if a regular joe schmo hasn't heard of them, I'm willing to bet they weren't 'top 10 ever' material in any category as broad as most influential in rock.
Can't say I'd mention anyone that hasn't already been said. Chuck Berry, Elvis, Beatles, Zeppelin, Floyd, Sabbath, Deep Purple all definitely influenced the music of the 70s onward. You look at Metallica, Maiden... they've had a huge impact on the 90s onward, as well as a huge impact on "metal", arguably a sub-genre of "rock".
Top influences of all time would have to be the originators back in the 60s and 70s.... as their influence continues to cascade down. When a band today says they were influenced by Metallica, who originally were influenced by Sabbath/Purple/Zeppelin, who then is 'more influential'? Clearly earlier acts.
Hendrix also has to be up there, as any prominent guitar player from the 70s/80s heard his music and had no idea that a guitar could make that kind of sound. The experimentation that he created has never been duplicated (imo).
