Answer by taking a quote from the following article:

The Beatles were an English rock band, formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential act of the rock era. In the early 1960s, their enormous popularity first emerged as "Beatlemania", but as the group's music grew in sophistication, led by primary songwriters Lennon and McCartney, the band were integral to pop music's evolution into an art form and to the development of the counterculture of the 1960s. Their continued commercial and critical success assisted many cultural movements--including a shift from American artists' global dominance of rock and roll to British acts (British Invasion), the proliferation of young musicians in the 1960s who formed new bands, the album as the dominant form of record consumption over singles, the term "Beatlesque" used to describe similar-sounding artists, and several fashion trends.

The Beatles' impact on the US was particularly strong, where a garage rock phenomenon had already begun, with hits such as "Louie Louie" by the Kingsmen. The movement received a major lift following the group's historic appearance on The Ed Sullivan Show watched by a record-breaking viewing audience of a nation mourning the recent death of President John F. Kennedy. Bill Dean writes: "It's impossible to say just how many of America's young people began playing guitars and forming bands in the wake of The Beatles' appearance on the Sullivan show. But the anecdotal evidence suggests thousands - if not hundreds of thousands or even more - young musicians across the country formed bands and proceeded to play."  Tom Petty, who played in two garage bands in Gainesville, Florida during the 1960s, is quoted mentioning the Beatles' appearance on The Ed Sullivan Show and how it influenced him to be in a band. According to him: "Within weeks of that, you could drive through literally any neighborhood in Gainesville and you would hear the strains of garage bands playing ... I mean everywhere. And I'd say by a year from that time, Gainesville probably had 50 bands." For many, particularly young baby boomers, the Beatles' visit reignited the sense of excitement and possibility that had been momentarily taken by Kennedy's assassination. Much of this new excitement would be expressed in music, sometimes much to the chagrin of parents and elders, as kids raced to start bands by thousands, and this proliferation of new groups was not limited to the United States.  While the Beatles are often credited for sparking a musical revolution, research conducted by the Queen Mary University of London and Imperial College London suggests that the changes sparked by the band were already developing long before they entered the US. The study, which looks at shifts in chord progressions, beats, lyrics and vocals, shows that American music in the beginning of the 1960s was already moving away from mellow sounds like doo-wop and into more energetic rock styles. Professor Armand Lero argues that the Beatles' innovations have been overstated by music historians: "They didn't make a revolution or spark a revolution, they joined one. The trend is already emerging and they rode that wave, which accounts for their incredible success." Beatles biographer Mark Lewisohn disagreed with the research by Queen Mary University, saying it "[doesn't] stack up ... Speak to anyone who was a young person in the US when The Beatles arrived and they will tell you how much of a revolution it was. They were there and they will tell you that the Beatles revolutionised everything." CANNOTANSWER

Where there any other impact on the future rock bands?

Svar genom att ta ett citat från följande artikel: The Beatles var ett engelskt rockband, bildat i Liverpool 1960. Med medlemmarna John Lennon, Paul McCartney, George Harrison och Ringo Starr blev de allmänt ansedda som rockerans främsta och mest inflytelserika handling. I början av 1960-talet växte deras enorma popularitet först fram som "Beatlemania", men i takt med att gruppens musik växte i förfining, ledd av primära låtskrivare Lennon och McCartney, var bandet en integrerad del av popmusikens utveckling till en konstform och till 1960-talets motkulturs utveckling. Deras fortsatta kommersiella och kritiska framgång bistod många kulturella rörelser - bland annat en övergång från amerikanska artisters globala dominans av rock and roll till brittiska akter (British Invasion), spridningen av unga musiker på 1960-talet som bildade nya band, albumet som den dominerande formen av skivkonsumtion över singlar, termen "Beatlesque" brukade beskriva liknande-ljudande artister, och flera modetrender. The Beatles påverkan på USA var särskilt stark, där ett garagerockfenomen redan hade börjat, med hits som "Louie Louie" av Kingsmen. Rörelsen fick ett stort lyft efter gruppens historiska framträdande på The Ed Sullivan Show som bevakades av en rekordstor tittarpublik av en nation som sörjde president John F. Kennedys nyligen bortgång. Bill Dean skriver: "Det är omöjligt att säga hur många av Amerikas ungdomar som började spela gitarr och bilda band i kölvattnet efter The Beatles framträdande på Sullivan-showen. Men de anekdotiska bevisen tyder på att tusentals - om inte hundratusentals eller ännu fler - unga musiker över hela landet bildade band och började spela." Tom Petty, som spelade i två garageband i Gainesville, Florida under 1960-talet, citeras nämna Beatles framträdande på The Ed Sullivan Show och hur det påverkade honom att vara med i ett band. Enligt honom: "Inom veckor av det, du kunde köra igenom bokstavligen vilken stadsdel i Gainesville och du skulle höra stammar av garage band spelar ... Jag menar överallt. Och jag skulle säga vid ett år från den tiden, Gainesville hade förmodligen 50 band." För många, särskilt unga bumersungar, återuppstod Beatles besök känslan av spänning och möjlighet som tillfälligt hade tagits av Kennedys mord. Mycket av denna nya spänning skulle komma till uttryck i musik, ibland mycket till föräldrarnas och de äldstes förtret, eftersom barnen tävlade om att starta band med tusentals, och denna spridning av nya grupper var inte begränsad till USA. Medan Beatles ofta krediteras för att ha utlöst en musikalisk revolution, tyder forskning som utförts av Queen Mary University of London och Imperial College London på att de förändringar som startades av bandet redan höll på att utvecklas långt innan de kom in i USA. Studien, som tittar på skiftningar i ackordprogress, taktslag, texter och sång, visar att amerikansk musik redan i början av 1960-talet var på väg bort från fylliga låter som doo-wop och in i mer energiska rockstilar. Professor Armand Lero argumenterar för att Beatles innovationer har överdrivits av musikhistoriker: "De gjorde ingen revolution eller satte igång en revolution, de anslöt sig till en. Trenden är redan på frammarsch och de red den vågen, vilket förklarar deras otroliga framgång." Beatles levnadstecknare Mark Lewisohn höll inte med om forskningen av Queen Mary University, säger det "[inte] stapla upp ... Tala med alla som var unga i USA när The Beatles anlände och de kommer att berätta hur mycket av en revolution det var. De var där och de kommer att berätta att Beatles revolutionerade allt." CANNOTANSWER Där det finns någon annan påverkan på de framtida rockbanden?
