Nor does this invention maintain a constant Internet connection, provide a mobile device that functions both as a cell phone and a regular hand set.  
       OBJECTS AND ADVANTAGES  
       [0008]     The present invention comprises: a base and mobile telephony device having a display that allows constant access to the Internet, (i.e. via DSL, satellite micro wave, and/or other methods) of access to web pages, provides Broadcast Software to create and view customized broadcasted announcements/advertisements (announcement/ad), email and Internet access via integrated Internet Service Provider (ISP) software, web hosting of announcement/ads, a web browser and wireless communication technologies.  
         [0009]     This is partially achieved by proprietary Broadcast Software (“BS”), a web browser, an Internet Service Provider (“ISP”), and hosting services.  
         [0010]     Broadcast Software will allow business entities (businesses, government and others) Broadcast Announcement/ad Capabilities (“BAC”) twenty four hours a day. Broadcast Software will have pre-designed templates that will allow for the production of custom announcement/ads that will broadcast primarily on display to each Internet Protocol (IP) address, and telephone number of present invention. Web portals will also be recipients of Broadcast Software productions also accessible from a personal computer when URL (Universal Resource Locator) is searched on WWW (World Wide Web).  
         [0011]     Broadcast software will have, but not be limited to the ability for the back-end user (business entity) to create an announcement/ad to be broadcasted by selecting front-end page set-up template, demographics (who will see the announcement/ad), “run” time schedule and, broadcast allocation areas (i.e. back-end user/business entity will have options as to where part or all of their announcement/ad information will appear when front-end user selects various functions from base and/or mobile device).  
         [0012]     Broadcast software will also allow business entity to send individual updates to their recipients or customers, track performance and usage of current and past announcement/ads, make payments and complete other electronic business functions currently in use in today&#39;s market. Broadcast Advertising Interaction (“BAI”) allows the front-end user to interact with content shown on display by responding to viewed media, such as making a purchase, requesting information, saving announcement/ads or becoming a customer.  
         [0013]     Above functions are combined with telephone components, where phone calls can be made and received via constant Internet access or the Public Switched Telephone Network (“PSTN”) or land based method or wireless service.  
         [0014]     A Direct Access Menu (“DAM”, i.e. which provides users external push button access to functions and features from base and mobile units such as Call Logs, Personal, Yellow Pages and Announcement/ad Directories, Security Settings, Purchases/Billing/Payment Index).  
         [0015]     Mobile unit is an Internet ready, mobile device that provides wireless or cellular telecommunication but within proximity to base unit Same device is communicably connected with base unit via a wireless connection (i.e. technology like “Blue Tooth” or similar). Whereby, incoming and outgoing calls no longer access wireless telecommunication (cellular) network to be completed, by utilizing telephony connection of base unit, thereby conserving minutes by minimizing cellular use.  
         [0016]     Mobile device also provides access to camera component, announcement/ads, email and other telephone functions.  
         [0017]     Base and mobile devices also provide but are not limited to: internal high speed modem, microprocessor, RAM memory, wireless communication receiver and transmitter, Universal Power Supply (“UPS”). Base unit provides ac/dc cord, telecommunications cord, peripheral ports (i.e. for external key board, monitor, cell phone charger, palm charger) combined with other standard components necessary to achieve this invention.  
         [0018]     When utilizing current invention&#39;s dual telecommunication ability, users can now use their home phone as their cell phone and vice versa. The base and mobile unit communicates via wireless technologies telecommunication median to be used for incoming and outgoing calls is based on the proximity of the devices. Users can also have additional, uniquely identifiable mobile units (different telephone numbers and IP addressee) for family members or matching units (telephone numbers and IP addressee same as master)to use for dedicated purposes (i.e. one can be a home based “handset” and second could be cellular “mobile unit”).  
         [0019]     When utilizing the current invention&#39;s camera component, users can surveille an area with ease. The user only has to position mobile device consisting of camera component in the area to be watched. Images will appear on display of base unit or a receiving unit.  
         [0020]     In emergency situations, this device can serve as an emergency information center by utilizing its UPS system in the event of a power outage. Users will still have access to important instructions and updates offered via ISP and Broadcast Software (Internet or intranet) for as long as the backup power lasts.  
         [0021]     As a communication median, the Internet has the potential to be the most efficient and cost effective in mass reachability. The current invention provides an optimal means to disseminate information and advertise products and services.  
         [0022]     By using this invention, shopping could be encouraged by offering a revolving line of credit with standard telephone service. Users could apply purchases to their telephone bill, in addition to other methods of completing a purchase.  
         [0023]     Not only can the majority of home in the United States not receive the multitude of benefits the Internet provides, this technology void also indicates a tremendous forfeiture of revenue from nonexistent sales. This technology void has been termed the “Digital Divide” (“DD”)  
         [0024]     The present invention addresses the Digital Divide (“DD”) by combining Internet access and the ability to view and purchase from always on streaming advertisements and broadcasted media via a common household device, the telephone.  
         [0025]     Some users may also opt to customize what appears on their display by selecting desired content to be streamed (i.e. important email alerts, date/event alerts combined with photos, breaking news and stock prices, or even which business entity is advertising, the lowest cost of milk).  
         [0026]     Whichever manner is selected to access announcement/ads, this device gives users the ability to search Broadcast Software database for goods and services(locally or nationally), complete a purchase, and maintain a purchase history record.  
         [0027]     By broadcasting content on the current invention, companies, government entities and others can now target the most unique and exact target market for their message. For example, when a front-end user (also referred to end user) attempts to make a long distance telephone call, using the easily accessible (“DAM”) menus, they would now be able to compare broadcasted or advertised long distance rates by multiple carriers and complete the call using the best selection.  
         [0028]     Having a UPS, would especially be important during emergencies, or power outages because it would provide full power to the base device for a period of time, whereby business entities can send urgent messages, information and instructions.  
         [0029]     The Direct Access Menu (“DAM”) of this device also combines functions such as easy access to call history, personal and national directories and features such as the ability for the end user to program user settings, save favorite or regularly needed announcements (or company access),pay bills, view past purchases, receive and pay bills, and view a customer service area.  
         [0030]     The present invention will acclimate low to middle income households to the efficiencies of using the Internet at home. Primarily because they will not be required install programs, decide which hardware or software to purchase or learn how to operate a an unfamiliar device.  
         [0031]     This is also needed preparation for federal legislation that has already been mandated that requires homes built after  2010  be wired with multimedia, fiber optic cabling as a standard.  
         [0032]     There are other objects and advantages remaining in specification and drawings. There is nothing on the market that offers the same benefits as present invention does.
