There are speculations that Google may be participating in the Yahoo sale. Is the search engine conglomerate doing this to remove competition?

According to Inc., Yahoo is gearing up for its sale. The company's revenue has dropped by 15 percent and its earnings went down by 20 percent.

It was also noted that the company's three flagship properties, mail search and Yahoo.com, have been losing audience. Preliminary bids for the Yahoo sale are only accepted until Apr. 18.

"[Yahoo] is just not worth a candle unless, essentially, you got it at such a discounted price," Diller told "Bloomberg Go" in an interview. "All of us are serfs on the land of Google. I told Google, it's sensible to treat your serfs well. If you don't, they rise up, get on horses and kill you."

Kpopstarz reported that the Daily Mail is the latest company to be interested with the Yahoo sale. Apparently, the British website has already done discussions with other investors.

"Given the success of DailyMail.com and Elite Daily, we have been in discussions with a number of parties who are potential bidders," a spokesperson for the website said to WSJ. "Further updates will be provided as appropriate."

Meanwhile, Verizon and Alphabet Inc.'s main division, Google, is believed to be considering a bid for Yahoo's core business. AT&T Inc. and Comcast are said to have decided against bidding as well as Microsoft Corp., which lost a bid for the company in 2008.

Time Inc. is still in the evaluation stage. Private equity funds companies such as Bain and TPG are believed to have plans to make a run at the business.

The Washington Post speculated that Google may be planning to apply its "substantial ad prowess" to Yahoo's content and audience. At the same time, the search engine giant could be "eliminating a lesser rival in the process."

However, due to those reasons, Google may be monitored even closely by antitrust regulators. The company has not addressed the concerns.
