CROSS-REFERENCE TO RELATED APPLICATIONS
 This application is a continuation of U.S. application Ser. No. 13/243,010 filed Sep. 23, 2011, which is a continuation of U.S. application Ser. No. 13/098,984 filed May 2, 2011, which claims benefit of priority under 35 U.S.C. 119(e) to Provisional Applications No. 61/330,356 filed on May 2, 2010 and No. 61/405,817 filed on Oct. 22, 2010, all of which are incorporated by reference herein in their entirety.
 This present disclosure relates generally to the field of electronic commerce and, more specifically, to systems, methods and computer program products for online marketing, scheduling and booking of services using a calendar-based application.
 Online calendar applications have traditionally been used to store events, appointments and schedule information, which can be accessed by users from anywhere using computers, smart phones or other networked communication devices. Some calendar applications allow users to share their calendars with friends and relatives who also utilize these applications. Some applications provide event reminders via email or have text messages sent to a user's mobile phone. Other applications provide some customization options, such as customizable background images, calendar views and event reminder options. However, these online calendar applications have very limited business marketing utility. For example, online calendar applications have not been provided by internet publishers to be used by local businesses to discount and market their services to the publisher's consumers.
 Disclosed is a publisher-provided, web-based calendar for discounting, marketing, scheduling and booking services. The system provides customizable calendars that service providers can use to create schedules of available services and discounts, which are fed into a user-accessible online marketplace. System users can search services advertised in the online marketplace and schedule and book appointments with service providers through the online booking system.
 In one example embodiment, the system provides advanced discount offers functionality that allows service providers to create real-time discount offers for the advertised services. In one example embodiment, the discount offers can be created by service type, practitioner, date, time or other criteria. In another example embodiment, the system also allows service providers to granularly discount a single service or a group of services. The system also provides several different hierarchical views for creating discount offers, e.g., by practitioner and by service. In another embodiment, discount schedules can be created for a single day or repeat daily or weekly.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
 Example embodiments are described herein in the context of systems, methods and computer program products for online marketing, discounting, scheduling and booking of services using a web-based calendar application. Those of ordinary skill in the art will realize that the following description is illustrative only and is not intended to be in any way limiting. Other embodiments will readily suggest themselves to those skilled in the art having the benefit of this disclosure. Reference will now be made in detail to implementations of the example embodiments as illustrated in the accompanying drawings. The same reference indicators will be used to the extent possible throughout the drawings and the following description to refer to the same or like items.
 FIG. 1 depicts one example embodiment of an online service booking system. As shown, system 100 includes an application server 105 that hosts a service booking application 110 and associated inventory database 115 storing a schedule of booked and available service appointments associated with computers of service providers 120A and 120B and service users 125A and 125B. (Service provider(s) and service user(s) will also be indicated generally by the reference numerals 120 and 125, respectively.) The server 105 is accessible via a network 140, such as the Internet, by computers of service providers 120 and users 125. Service providers 120 may include, but are not limited to, beauty salons, health spas, sports clubs, barber shops and other local businesses (i.e., service providers) that provide services to clients (i.e., service users) with associated appointments. In one example embodiment, system 100 provides a customizable Web-based service provider interface 130 to providers 120 by means of which a provider can create a schedule of available appointments by service, practitioner, date, time or other criteria. In another example embodiment, system 100 provides a Web-based user interface 135 to users 125 for searching availability, discounts, and ratings of available services and booking one or more appointments with service providers 120.
 It should be noted that in another embodiment some of the functionality of the booking application 110, including but not limited to, provider and user interfaces 130 and 135, may be implemented as applications directly on the computers of the service providers 120 and service users 125. In this case, the inventory database 115 may be maintained on a remote server hosted by the booking application developer or in the cloud, such as Amazon® Elastic Compute Cloud. It should be also noted that in various embodiments, computers of the service providers 120 and service users 125 may include, but not limited to, personal computers, laptops, netbooks, tablets, digital media players, personal digital assistants, smart phones, or other types of digital devices.
 FIG. 2 shows an example embodiment of a calendar-based service provider interface 130 of the application 110. Using this interface, service providers 120 can register/access the online booking application 110, create profiles and accounts 210, create/view schedules of appointments 220, enter discount information 250 and perform other functions. The registration/access process may involve creating user name and password, providing contact information, providing service menus, providing billing information and the like. The business profile 210 can be used to enter information about the business in general, about available practitioners, and about the types of available services. The business account may be used to view all information maintained by the booking application 110.
 The service provider 120 may also use interface 130 to enter/update/view appointment scheduling information 220. In one example embodiment, service appointments may be made by service users 125 through the service user interfaces 135 and displayed as an appointment block in the appropriate year/month/date/time slot of the calendar-based service provider interface 130. In another example embodiment, the application 110 can interface with third-party scheduling technologies and calendars, such as Mind Body Inc., SpaBooker®, Google® Calendar and Microsoft® Outlook®, via dedicated XML APIs to provide business profile information and pull availabilities from those calendars into the service provider interface 130 and to push appointments booked by system users through the application 110. This embodiment exemplifies the publishing functionality of the application as it moves availabilities from a pure calendaring system (i.e. Google® Calendar) into a publisher marketing environment.
 As shown in FIG. 2, the calendar-based service provider interface 130 shows a daily operating schedule of Henry Depaul Beauty Salon for Jul. 5, 2010. As shown, there are five (or more) practitioners working on that day, including Andrew U., Dana R., Harris N., Jess A. and Mabel H. They are available for appointments from 10 am to 7 pm. The interface 130 also shows that service providers Dana R. and Jess A. have two scheduled appointments 230 and 240 at 4:15 PM. Dana R. was booked directly through the Salon. Jess A. was booked via the booking application 110. The directly or indirectly booked appointments 230 and 240, respectively, can be designated, for example, using different colors. The appointment blocks 230 and 240 can indicate the names of the users/clients that made these appointments and other information. Since appointment block 230 was made directly through the Salon, and not through the booking application 110, information about this appointment could have been entered manually by the service provider 120 or pulled automatically by the application 110 into the service provider interface 130 from the third-party scheduling system used by the service provider 120. This appointment information may be shown both in the service provider interface 130 and in the service user interface, 135, so that service users 125 know which time slots are available for booking and which have already been booked.
 In one example embodiment, the service provider 120 can designate time blocks when one or more service providers are unavailable for appointments using "unavailable" tool 260. In the example in FIG. 2, all practitioners have been marked as unavailable from 2:30 PM to 4:00 PM, as shown by the shading. Unavailable blocks can also be pulled automatically by the application 110 into the service provider interface 130 from the third-party scheduling system used by the service provider 120.
 In another example embodiment, service provider interface 130 allows service providers 120 to create real-time discounts for their services by practitioner, service, date, time or other criteria. For example, using a discount tool 250, service provider 120 can indicate in the calendar the days and times when service rates of one or more practitioners have been discounted. In the example in FIG. 2, all practitioners have discounted rates on Jul. 5, 2010 from 11 AM to 2 PM, as shown by shading.
 In one example embodiment, the discount tool 250 gives service providers 120 several different options for creating discount offers, such as by practitioner, by service, by date and time. FIG. 3A shows one example interface of the discount tool 250 that can be used for creating different discounts offers for different practitioners 310. As shown, the service provider 120 can set the same discount for all or different discounts for different practitioners. Furthermore, the discount offer may apply to all or specific services provided by each practitioner. For example, in case of Andrew U., a 20% discount is provided on glamour blowout services, and a 40% discount is provided on all coloring and all up-do services, while all services of Dana R. have a 50% discount offer.
 FIG. 3B shows another example interface of the discount tool 250 for creating discount offers for different services 320. As shown, the service provider 120 can set a single discount on all available services, or different discounts on subsets of services, such as all blowout services and all glamour blowout services. Furthermore, for each subcategory of service, the service provider 120 can indicate which practitioners have additional discounts, such as Jess A. has an additional 50% discount on glamour blowout services, while Andrew U. has an additional 20% discount on the same service.
 In another example embodiment, the discount tool 250 also allows service providers 120 to specify the appointment date and time 330 when discount offers are made available to the service users. As shown in FIG. 3B, the discounts may be offered, for example, on particular days of the week, on particular dates/times or never end.
 Yet in another example embodiment, the discount tool 250 allows service providers 120 to set a function that will automatically discount a single service or a group of services in an effort to maximize revenue to the business. The discount tool 250 can be configured to automatically increase or decrease discounts offered on a particular service or practitioner based on behavioral data and/or by an amount defined by the business (e.g., 10%) in predetermined time increments (e.g., weekly, daily or hourly) for particular blocks of time, to particular groups of users (i.e., users new to the business, in a certain geography, etc.). To that end, the service provider may specify various business decision rules (or use business rules based on behavioral data provided by the booking application 110) that gradually adjust the rate of discount based on lack or excess of bookings of a particular service or practitioner on a particular day or time. For example, a sale on a particular service may start at a high discount, e.g., 80% at 9 AM, when business is generally slow. Then, the discount tool 250 will automatically decrease the rate of discount for an appointment time by, for example, 10% every hour on the hour, until the discount reaches 0% by the end of the day. In an alternative embodiment, a service provider 120 may manually adjust the offered discount without use of the discount tool 250. In addition, during each discount adjustment, the system 100 may advertise the current discount offers to a targeted group of users via email notification, banner ads, SMS text messages, social media, and other forms of advertising and communication platforms.
 Once the schedule of available appointments and associated discounts are created by service providers 120 using interface 130, this information is stored in the account of the service provider 120 and fed into a common online marketplace of all available services and providers hosted by the booking application 110. This online marketplace is accessible to service users 125 via service user interfaces 135.
 FIG. 4 shows one example embodiment of the service user interface 135. Using this interface, service users 125 can search the online marketplace for available appointments using service type, appointment date/time range, service rating, business location, discount amount, and/or price range. The booking application 110 searches its database of available services and displays a listing of service providers and available appointments for services matching the user-specified search criteria. For example, in response to a user searching for providers of women's haircuts in New York on April 28 through April 30, the booking application 110 displays several New York salons, which provide the requested service on the given dates, as well as the pricing and discount information specified by the service provider 120. The user can view detailed information about the service provider and book an appointment with the service provider by clicking on the specific entries 410 in the displayed list.
 FIG. 5 shows an example embodiment of a calendar-based user interface 135 for one of the service providers listed in the search results list in FIG. 4. The interface shows a weekly view of available appointments for the service provider and the associated pricing and discount information for each appointment. Monthly and daily views of the available appointments information are also available. In the case where additional practitioner-specific discount information has been specified by the service provider 120, this information may also be displayed, so that the user 125 can make appointment selection based on all available discount information. Once the user selects one of the available appointments, the service provider account is updated to reflect that an appointment has been booked, as shown, for example, by block 240 in FIG. 2, and an email message can be sent to the user 125 confirming this booking.
 In one example embodiment, the booking application 110 can dynamically create specific discount offers on services from the services inventory based on users' history of using different services, users' reviews and other criteria. For example, the application 110 may identify what users have booked before, looked at, indicated as being interested in, the number of times they returned to a particular business, and other criteria to determine what services should be advertised to the service users 125. The application 110 can then send targeted advertisements to service users 125 using emails, text messages (e.g., SMS), mobile applications, as well as other communication means. FIG. 6 shows one example of a targeted email that advertises discounted services to a service user 125 who previously booked services at Biondi's.
 The targeted emails may be sent to the users on an interval based on the date of their last appointment according to service category (e.g., 3 months for a woman's haircut, 30 days for bikini waxing, etc.). The marketing copy and photos for reach advertisement may be the same for each service category, but the individual services/discounts are targeted to the unique user. When the user clicks "book" button 610, the service is added to her cart and she is shown a pop-up on the site asking if she would like to book now. When the user clicks book now, she goes to the appointment time selection page shown in FIG. 5 to select the desired appointment date/time.
 FIG. 7 illustrates one example embodiment of a method of operation of the online booking application. At step 710, the application provides to a service provider a calendar-based service provider interface for creating a schedule of services provided by the service provider. At step 720, the service booking application receives from the service provider through the interface a schedule of available services, which includes the name of the service, the date and time when the service is provided, the name of the practitioner who performs the service, the price of the service and a discount offer. At step 730, the application stores the received schedule of services in an inventory database. At step 740, the application retrieves from the inventory database information about appointments booked by a service user with the service provider. At step 750, the application displays the appointment information in the corresponding time slots in the calendar-based service provider interface. At step 760, the application retrieves from a third-party appointment booking system of the service provider information about appointments booked by a service user. At step 770, the application displays the retrieved appointment information in the corresponding time slots in the calendar-based service provider interface. At step 780, the application generates a targeted discount offer for a service user based on, for example, the user's history of using the service or other discount recommendation criteria specified by the service provider. At step 790, the application electronically sends, e.g., by e-mail, the targeted discount offer to the service user. The generated targeted discount offer may be published in other ways as well, for example through the interstitial ads, pop-up ads, mobile ads sent to the user's mobile phone, or other online publishing mechanisms known in the art.
 FIG. 8 illustrates another example embodiment of a method of operation of the online booking application. At step 810, the application receives from a service user search criteria indicating one or more of a type of service, a date of service and a price of service searched by the service user. At step 820, the application searches schedules of available services in an inventory database. At step 830, the application displays in a calendar-based service user interface a schedule of available service appointments and associated discount offers that match the search criteria. At step 840, the application books with a service provider a service appointment for the service user. At step 850, the application stores information about booked appointments in the inventory database. At step 860, the application sends a notification about the booked appointment to the service provider and the user. At step 870, the application retrieves from the inventory database information about appointments booked by a service user with the service provider. At step 880, the application displays the appointments information in the corresponding time slots in the calendar-based service user interface.
