The two bitter Internet rivals are trying to expand their turf. Yahooligans and Googlers faced off in an aptly named "Battle over the Net" tennis tournament this weekend. (Photos are here.)
Yahoo won by a short margin, 163 to 157, according to Cedric Beust, a Google software engineer.
"The two companies fielded an impressive 20-30 players each, and started playing doubles at 9 am in the beautiful Stanford Stadium," Beust wrote on his blog. "The format made for quick and deadly games (eight games total, no ads) and at the end, the referees tallied the total number of games scored by each side."
