It has been quite a day for the business industry with the giant online company, IAC, revealing their staggering $500 million unsolicited offer to get a hold of the rising Angie's List earlier today. The offer comes on Wednesday.

The IAC or InterActivCorp, which is owned by Barry Diller, recently made an unsolicited bid on Wednesday to Angie's List, a website known for its reviews on local businesses and a rival of HomeAdvisor, a company that IAC also bought.

Reuters reports that IAC is insisting to get Angie's List at $8.7 per share, which represents a premium of 10.5 percent according to Angie's List's price that was disclosed that day as well. However, Angie's List revealed that shares were trading at $8.88 per stock after market.

Meanwhile, the offer stands and Angie's List received the unsolicited bid. However, Reuters revealed that the company's stockholders were advised to be still for the time-being and hold off on any actions regarding the offer priced at exactly $512 million in cash.

However, Angie's List released a statement obtained by CNN, saying that it will review and evaluate the offer.

Fox Business further said that Angie's List is also a company that lets one user to hire almost any kind of professional services (e.g., a painter, babysitter, etc.). The report notes that IAC may want to acquire this service to further enhance its already gigantic business.

Apparently, according to Reuters, IAC may have seen an opening towards Angie's List because of its losses in market share, including its subscribers, since the company charges membership fees unlike TripAdvisor and Yelp, which gives information such as reviews and ratings for free.

Meanwhile, CNN notes that IAC has a wide-reach of brands including Ask.com, About.com, Match.com, Vimeo and HomeAdvisor. Furthermore, IAC's offer comes with a proposal that it might also be combining Angie's List and HomeAdvisor through a tax-free, stock-for-stock exchange, Reuters reports.

Even TCS Capital Management, the company that owned 9% of Angie's List urged that Angie's List combine with HomeAdvisor, Reuters revealed. It could be a perfect match since HomeAdvisor is known to be used by consumers to match them with pre-screened home services professionals in the United States including in France and the Netherlands, Reuters further reports.

The story is currently developing and there are no new updates as of the moment from the two companies if and when they will be agreeing on the surprising bid of IAC towards Angie's List.
