There are no right or wrong answers to this question because it's all a matter of opinion, but who was / is the greatest rock group of all time???
I've got to say the Beatles. They weren't my favorite group but they had such an impact globally. During their years together they outsold everyone else in the rock world, had more #1 hits, made more movies. Everyone talked about Beatlemania. It was real. The Beatles were incredible. Their rock crossed over generations. Even my parents liked "Yesterday".
#2 The WHO is my personal favorite group because they seemed to be the most creative while reflecting the anger, boredom, and rebellion of teens during their time accurately. They were the first to attempt rock opera which was a cool journey not attempted previously in my memory. And Roger Daltrey and Pete Townshend are still alive which keeps them semi relevant 60+years later. Won't Get Fooled Again is my personal favorite rock song of all time and remains my anthem.
#3 And Led Zeppelin because of the changes they brought to radio that have remained with us. Prior to the advent of Led Zep, music radio was all about hit songs and top of the charts, largely 2 min songs. Led Zeppelin ushered in album rock which was featured on their albums which became huge sellers. Their long album hits were huge in my area of the country where there are lots of colleges and universities and people wanted to engage in other activities during album listening as did the djs who played those ballads. It was like discovering something new.

Once the change came, it stayed.
So who were/are your favorite band(s) of all time?
