The full record of Anand's victory is on my page 2000 FIDE Knockout Matches, and I have links to contemporary accounts from Hindu.com on another page, Reports from The Hindu. Although the domain for those reports changed between 2000 and 2011, it is remarkable that the originals are still available on the web. The following table shows that the year 2000 is the earliest where we have such reports.
2000: 679 results
2005: 3600 (San Luis, won by Topalov)
2007: 5690 (Mexico City, won by Anand)
2008: 5740 (vs. Kramnik)
2010: 5680 (vs. Topalov)
I can't explain the big drop in 2011, but the numbers still work out to more than 5.6 reports per day. Is there any other country with so much interest in its top chess player?
(*) Re the 'C19: 2000-01' terminology, there is no good reason why it shouldn't be labeled 'C19: 2000'. Most of the zonals took place in 2000, and the last round of the final match was played before the end of that year. The zonals for the next cycle, C20: 2001-02, were played in 2001, and the first six rounds of the next FIDE knockout championship were played near the end of that year. The final, where Ponomariov beat Ivanchuk, was played in 2002.
