Bono and Paul McCartney opened London's Live 8 concert
The channel's live coverage of the global concerts won an average audience of 6.6 million.
Rock band Pink Floyd's album sales soared by 1,343% after their comeback appearance at London's Live 8 concert.
Performers The Who and Annie Lennox also registered big sales increases. Meanwhile the BBC received 400 complaints after onstage swearing.
BBC apology
Saturday's average Live 8 ratings of 6.6 million represented 37.2% of the total TV viewing public at that time.
The Live 8 ratings failed to match the 20.7 million UK viewers who watched England's football defeat to Portugal in Euro 2004 last June.
They were also beaten by last year's finale of ITV1's I'm a Celebrity... Get Me Out of Here, which drew an average of 10.9 million viewers.
More than 140 TV channels showed the events, along with some 400 radio stations, and internet streams.
Organisers estimated that 85% of the world's population would have been able to tune into the event.
Madonna and US star Snoop Dogg were among those to use bad language prior to the 2100 BST watershed.
The BBC, which did not use a time delay during the broadcast, apologised for the swearing.
LIVE 8 STARS' ALBUMS BOOST 1 Pink Floyd - Echoes: The Best of Pink Floyd - 1343% 2 The Who - Then and Now - 863% 3 Annie Lennox - Eurythmics Greatest Hits - 500% 4 Dido - Life For Rent - 412% 5 Razorlight - Up All Night - 335% 6 Robbie Williams - Greatest Hits - 320% 7 Joss Stone - Mind, Body and Soul - 309% 8 Sting - The Very Best of Sting & The Police - 300% 9 Travis - Singles - 268% 10 Madonna - Immaculate Collection - 200% Source: HMV
She added: "Millions of people enjoyed our 12 hours of live broadcasting.
"We are sorry if any offence was caused."
However the number of Live 8 complaints did not exceed the 4,000 complaints made to the BBC in May concerning its new 3D TV weather map.
The corporation also received 47,000 complaints before broadcasting Jerry Springer the Opera on 8 January, when hundreds of protesters rallied outside BBC buildings.
Current acts such as Razorlight and singer Joss Stone also enjoyed increased music sales following their Live 8 appearances.
Increased record sales for Live 8 performers, compared with sales last Sunday, were good news for "iconic acts" including Pink Floyd, according to HMV's Gennaro Castaldo.
"Even allowing for the relative nature of this exercise, where back catalogue sales of the more established acts are being measured from a fairly low base, this snapshot shows that Live 8 is having a marked effect on sales - just like its predecessor 20 years ago," he said.
Mr Castaldo added that the effect would become more pronounced during this week.
Brytyjska telewizja BBC, która realizowała transmisję koncertów Live 8 w miniony weekend, otrzymała wiele skarg i zażaleń na język używany przez występujące gwiazdy, takie jak Madonna i Snoop Dogg.

Od czasu ubiegłorocznego skandalu podczas Superbowl, finału rozgrywek zawodowej ligi futbolu amerykańskiego, kiedy to pokazana została pierś Janet Jackson, stacje telewizyjne były krytykowane za brak opóźniania przekazywania obrazu, który mógłby być w tym czasie wstępnie cenzurowany. Pozwoliłoby to uniknąć wulgarnych i niestosownych scen, które mogłyby być oglądane także przez dzieci.

Pomimo tego, koncerty Live 8 były pokazywane na żywo. Przez to stacje telewizyjne nie mogły uniknąć choćby pojawienia się wulgarnych słów w czasie transmisji.

Jak powiedziała rozmówczyni ze strony BBC, stacja ta otrzymała prawie 400 skarg w związku z niestosownym językiem używanym przez występujące gwiazdy. ''"Miliony ludzi bawiło się w czasie 12 godzin naszej transmisji na żywo. Jest nam przykro, jeśli kogokolwiek skrzywdziliśmy" - dodała.

Gwiazdy krytykowane za używany język, to między innymi Snoop Dogg, Madonna, Johnny Borrell (Razorlight) i Billie-Joe Armstrong (Green Day).
